Music Downloader & MP3 Player · VideoMusic-Player Studio

Two identical "free music download" apps launched on the same day: 220k installs behind them is a Vietnamese app-factory

What it is An Android music downloader plus a local MP3 player. Songs come from ccMixter's free CC-licensed catalog, and it makes money from ads.

Why it took off Demand for free offline listening has always been there. It used search-heavy titles and package names, prompted for ratings in pop-ups to reach 4.7 stars, and as one of a batch of same-template apps from Vietnam it was pushed across Australia, Germany, and the Netherlands.

CHow you could follow it Stop building music downloaders. Instead, take the flow of "free compliant content source + open-source base + keyword-heavy title + rating prompt + interstitial ads + one app per package per country" and move it into niches still not saturated with templates, such as audiobooks, sound effects and ringtones, or white noise. Test with a small budget whether it pays back.

Grade C: the playbook is clear and worth learning from, but the category is already flooded by Vietnamese and Chinese studios using the same template (over 19 same-named packages this year). This app is just one batch and past its peak, and it carries copyright and takedown risk, so following it isn't worth much. Few people know about it yet

In Sep 2026 3, two different developer accounts on Google Play each launched an app called "Music Downloader & MP3 Player," with word-for-word identical descriptions and package names made of the same few English words in a different order. Two months later, one had 222k installs and had entered the music free charts in Australia and Germany. It has nothing new in its product; what's worth looking at is the batch-packaging and country-by-country rollout behind it. Cloning another one isn't worth it.

Two twin packages

Start with the package names. This one is musicdownloader.musicdownload.downloadmp3musicfree.downloadmusic, by a developer called VideoMusic-Player Studio. The other app launched the same day is net.musicdownload.downloadmp3music.downloadmusic, by a developer called MyFirstAppGame. The descriptions match word for word, including the closing disclaimer that "all music comes from ccMixter," and both privacy policies sit on pages in the "username.github.io/privacy/privacy.html" format.

The VideoMusic-Player Studio account has only this one app. Its developer email is a personal Gmail with a name that looks Vietnamese, and its website is an empty Vietnamese-language Blogger blog. AppBrain shows this developer as "active for about one month."

By Nov 6, the other twin had 237k installs, charting mainly in the US and Canada; this one had 222k installs, charting in Australia, Germany, the Netherlands, and South Africa (Google Play installs and country category charts, 11-06). The two barely compete in the same countries.

What it is

A music downloader plus a local MP3 player. The store description says it can "search public-licensed catalogs, save to your phone in one tap, and play offline." Scrolling down, the disclaimer says the tracks come from ccMixter's public API and are independent music under CC BY-SA 3.0. So what you can download isn't pop music, but free work released by independent artists.

The player half has a long feature list: gapless playback, ReplayGain volume leveling, folder allow/deny lists, a pure-black OLED theme, and colors picked from album art. That list nearly matches one-to-one with Retro Music Player, a GPL open-source local player, which suggests it was modified from an open-source project. Inference, not verified by unpacking the APK

Free, labeled "contains ads," no in-app purchases.

How the 220k installs built up

The first four weeks after launch were slow, reaching only 1k installs by Oct 13. It accelerated in weeks five to seven, with about 12k new installs in the week of Oct 62, the peak. It has declined steadily since: about 26k in the week of Oct 22, 7k in the last 38 days, and by Nov 5 and 6 roughly 4 thousand a day. (Weekly data before October is third-party AppstoreSpy estimates; November figures are Google Play installs.)

On the charts it appeared only in the music free category, never in the overall or top-grossing charts. In Germany it fell from its best rank of #31 in Oct 26 to #6 in Nov 55; in Australia its best rank in Nov was #5 on day 26,6 35. Going by this curve, it has already passed its peak.

Four things pushed it up:

The title is the search term. "Music Downloader" and "MP3 Player" are the two biggest search terms in this category, so the title uses them directly. The package name stacks musicdownloader, musicdownload, downloadmp3, musicfree, and downloadmusic. The end of the description repeats "MP3 downloader, audio downloader, local player, offline music."

4.7 stars, but almost nobody writes anything. The rating count went from 29 in Oct to 5,507 in Nov (4,690 to 6 in the source), adding a steady 90 to 120 ratings a day, about 2% of new installs. Only 9 ratings came with written text. So many people leave stars and nothing else, which looks most like an in-app prompt asking for a rating inferred. The new package starts with 4.7 stars, which helps search ranking and click-through.

One account, one package, rotating new launches. Following the threads (package names reusing the same words in different orders, privacy pages on one template, disclaimers word-for-word identical), at least 6 sibling packages can be linked:

Package prefixDeveloper accountLaunchedInstalls (11-06)
musicdownload.musicdownloader…AppUtil-Studio08-14297k
downloadmusic.downloadmp3music…AppTools STUDIO08-25126k
freemusicdownload.downloadmusic…TubeVideoPlayer08-29144k
musicdownloader.musicdownload… (this one)VideoMusic-Player Studio09-03222k
net.musicdownload.downloadmp3music…MyFirstAppGame09-03237k
music.downloadmp3music…Lab-App-Tools10-1241k

The six packages add up to roughly 1.07M installs, with a new package every week or two, each under a different developer account. Several developer emails use the name of a Vietnamese company (Google Play installs, 11-06). Going further back, a wave of same-name Vietnam-linked packages starting with com.musicdownloader.* ran in spring and summer this year, adding up to over ten million installs. When one package ages out or gets delisted, the next one takes over. Whether it's one operator or several Vietnamese studios sharing a template supplier can't be determined from the outside.

Split by country. The sibling packages hardly overlap in the countries where they chart. This one is in Australia, Germany, the Netherlands, Sweden, and South Africa. The twin is in the US and Canada. The freemusicdownload one is in France, Italy, and Mexico. The earlier wave ran in Southeast Asia, the Middle East, Nigeria, and Brazil. This looks like localization or ad budgets allocated by country inferred. Paid acquisition can't be verified: none of these packages show up in the public ad libraries of Meta, TikTok, or Google. But the first four weeks were slow, then in week five it jumped to #26 in the Australia and Germany categories, which leaves room for a small budget pushing the chart and natural search taking over inferred.

Searching X, TikTok, and the open web turns up no one discussing it. Only automated aggregator pages like AppBrain and Similarweb.

Where the money comes from

It only runs ads. No in-app purchases, so it never reaches Top Grossing, and its revenue is invisible from outside. The catalog comes from free APIs, and the player appears to be a modified open-source build, so content and development costs are close to zero. Australia, Germany, and the Netherlands are high-CPM countries, so a package with 220k installs running for two months very likely has positive ad margins inferred.

Who it's competing with

It is itself a copycat. At least 19 Google Play apps starting with "Music Downloader" have launched since June this year, and most of them are this same template.

If it were you

The verdict: Don't build the next music downloader. The category is already saturated, with Vietnamese and Chinese studios filling it using the same template and dozens of developer accounts. This is already the fourth or fifth batch off the assembly line, and it's past its peak. What's worth learning is the process of producing and distributing packages, not the product.

Who it suits: Teams that already run multiple Google Play developer accounts, can do multilingual ASO, can calculate install cost and ad revenue per country, and can accept that when a package gets delisted they just switch to the next one.

Who it doesn't suit: Indie developers who want to build a product users keep using long-term; anyone with only one developer account who can't afford a ban; anyone worried about copyright and store-policy risk.

How to do it: Move the process to a category that hasn't been filled with templates yet, rather than rewording and rebuilding another music app. The formula: a free content source you can legally use (CC music, public-domain audiobooks, CC sound effects and ringtones, white noise) + an open-source local player or tool as the base (note that GPL requires you to open-source your changes) + the big search term as the title and package name + a rating prompt + interstitial ads. Before you start, search your target keywords on Play. If the top 20 results are already a row of same-name packages, change the keyword inferred.

How to acquire users: Follow their approach: use the search term directly in the title and package name. Focus each package on three to five countries. Start with markets like Australia, Germany, the Netherlands, and the Nordics, where ad CPMs are high and competition is lower than in the US. Get the rating prompt working in the first week, establish a score first, then push for chart placement.

When to do it: There's no seasonal window. Packages like this live about six to eight weeks, and the window depends on when Google cleans up the category. If you try it, test one or two packages within a month and see if at least one country pays back. If not, stop.

What would show this read is wrong: ① By December, this package is still at over 4 thousand installs a day and has charted in more countries, which would mean it lasts longer than it looks and the category still has room for newcomers. ② Conversely, if sibling packages keep getting delisted and no new sibling packages appear after Oct 12, it means even these experienced operators think the math no longer works.

Why Music Downloader & MP3 Player (VideoMusic-Player Studio) made it

  • Package name: musicdownloader.musicdownload.downloadmp3musicfree.downloadmusic, Google Play, Music & Audio category
  • Developer: VideoMusic-Player Studio (developer email is a personal Gmail, phammaihuong1205200444@, a Vietnamese name; the website appmp3music.blogspot.com is an empty Vietnamese-language Blogger page; the privacy policy is hosted on a same-name github.io)
  • Launched: 2026-09-03; free, ad-supported (ad_supported=True), no in-app purchases
  • Data as of 2026-11-06 (googleplay library; historical curve filled in by AppstoreSpy, marked "AppstoreSpy est.")

Bottom line

It's one of a batch of Vietnamese "Music Downloader & MP3 Player" template packages, and the product itself has no differentiation. It got traction thanks to four things: a long-running need (free music downloads, offline listening); a compliance shell that passes Google Play review (the catalog is ccMixter Creative Commons music, and the player looks like a modified open-source local player); using the store's big search terms directly as the title and package name; and a matrix approach of one developer account per package, rotating launches, and country splits to scale. Monetization is ads. Each package runs its lifecycle in about 6 to 8 weeks, and this one is past its peak.

1. Data: how big it is and how it grew

Week 10-0569,068About +29k per week
Week 10-12131,526About +62k per week (peak)
Week 10-19174,265About +43k per week
Week 10-26196,350About +22k per week
11-06221,633+7 over the last 38,264 days; about 3,800 to 4,100 a day in 11-05 and 11-06
  • The daily install curve is sawtooth-shaped (for example 10-04 +24.5k, then 10-05 only +47). On the same days, other same-template packages jump together (10-04, 10-08, 10-12/13, 10-21). This is a trace of Google refreshing maxInstalls every few days, not an ad-spend pulse, so only the weekly averages are meaningful.
  • Ratings: 4,690 (10-29) → 5,507 (11-06), about 90 to 120 a day, roughly 2.3% of new installs; average 4.70. But only 9 ratings came with written reviews (app_snap.written_reviews), meaning almost all of them are stars tapped in an in-app prompt, with nobody writing text. This looks like an in-app rating prompt, but that can't prove the ratings are fake.
  • Charts (googleplay library chart_rank): only ranked in the free Music category charts. 11-06 Australia #35 (best ever #11-05 26), Germany #55 (best ever #10-31 26), Netherlands #118, South Africa #109; it has also charted in the Philippines, Sweden, and the UAE. Germany slid from #10-31 to #26 to #55, while Australia remains high. It has never made any overall or Top Grossing chart.
  • Revenue: no in-app purchases, not on Top Grossing, all income comes from ads (AdMob or similar). The amount can't be determined.

2. Competitors: who else does the same thing

"Free music download, offline playback" on Play is an old category with heavy oversupply. Titles starting with "Music Downloader" alone number 19 in the store, all launched after 2025-06.

Verdict: hundreds of competitors in the same category. Over 2026 years alone, the same Vietnamese team (or a few studios sharing the same code and distribution playbook) has shipped more than a dozen same-name packages in a row. This product isn't original; it's one "batch" in this matrix.

3. Growth tactics: where users come from

  1. Store search ASO (confirmed): the title "Music Downloader & MP3 Player" puts the two biggest search terms front and center. The package name stacks musicdownloader / musicdownload / downloadmp3 / musicfree / downloadmusic. The description ends by repeating "MP3 downloader, audio downloader, local music player, offline music".
  2. Small-account matrix, package rotation (confirmed): the following lines connect into one package family: the same few words reordered in the package name, github.io or hostingt2-N.web.app privacy pages, and word-for-word identical ccMixter disclaimers:
    • musicdownload.musicdownloader.freedownloadmp3music.downloadmusic (AppUtil-Studio, 08-14.3M, privacy page hostingt2-3.web.app)
    • downloadmusic.downloadmp3music.mp3musicfree.musicdownloader (AppTools STUDIO, 08-25.1M, privacy page luuq5768.github.io)
    • freemusicdownload.downloadmusic.mp3musicfree.downloadfreemusic (TubeVideoPlayer, 08-29.1M, privacy page hostingt2-4.web.app)
    • This app (VideoMusic-Player Studio, 09-3.22M)
    • net.musicdownload.downloadmp3music.downloadmusic (MyFirstAppGame, 09-3.24M)
    • music.downloadmp3music.mp3musicfree.appmusicdownloader (Lab-App-Tools, 10-1.24M, privacy page hostingt2-1.web.app)

Each package is under a different developer account. Several developer emails use Vietnamese company names (longhaivnsecurityservice.jsc, tginvestmentcons1member.coltd, donghaiprivate.enterprise). A new package goes up every week or two, and the 6 packages total about 1.07M installs. Earlier still, there was a wave of com.musicdownloader.* packages (MCVN JSC, Saigon Future JSC, HDVN, etc.) sharing the privacy-page bucket f005.backblazeb2.com/file/AppPrivacyPolicy/, totaling over ten million installs. With this setup, when one package is taken down or its chart ranking fades, the next one takes its place immediately.

  1. Split by country (highly credible, inferred): packages in the family chart in different countries and barely compete with each other. This app charts in Australia, Germany, the Netherlands, Sweden and South Africa; the net.* package launched the same day charts in the US and Canada; freemusicdownload.* charts in France, Italy and Mexico; the earlier com.* wave charts in Southeast Asia, the Middle East, Nigeria and Brazil. This looks like ASO localization or paid-acquisition budgets allocated by country.
  2. Paid acquisition (unconfirmed): no trace of it or its family packages in the Meta, TikTok (Europe) or Google ad libraries (these libraries only cover listed products, so finding nothing doesn't mean no spend). The first 4 weeks brought only 13k installs, then it jumped to 60k per week in weeks 5 to 7, reaching #26 in the category in high-CPM markets like Australia and Germany. That could be paid pushes (small UAC budgets to climb the charts, then riding organic search), or just Google search rankings rising. No direct evidence.
  3. In-app review prompts (highly credible): only 9 of 5,507 ratings have written text, and the average holds steady at 4.70. The 4.7 rating helps the new package rank higher in store search, one piece of the ASO loop.
  4. Content, creators, media (none): X (x-radar, last 30 days) returned 0 posts; it doesn't appear in the top 20 TikTok results for "music downloader app"; web search only turns up auto-indexed pages like AppBrain, Similarweb and APKPure.

4. Why it can break out

  • The demand is steady: people who want to listen to music offline for free without paying for a Spotify or YouTube Music subscription are always there on Android, especially in cheap-traffic markets like South Africa, the Philippines and Southeast Asia, with some in Western Europe and Australia too. Audiomack's 196M and com.atpc's 162M installs are proof.
  • The compliance wrapper lets it list and stay listed: Google Play doesn't allow downloading copyrighted content such as YouTube. This package family uniformly presents its source as the "ccMixter public API, CC BY-SA 3.0 licensed," which holds up in review. The player part is likely adapted directly from a mature open-source local player, so development cost is close to zero. (Reviews of the sibling package MusicPlayer AppStudio include remarks like "it downloads songs other apps can't" and "Lekompo (South African pop genre)," so whether ccMixter is really the only downloadable source is uncertain.)
  • Keyword-heavy title plus high ratings: the title and package name match search terms directly, and a 4.7 rating with steady new reviews is enough for ranking weight.
  • 矩阵和轮换:一伙人(或一个共享模板的工作室圈子)批量造包、分账号、分国家,单个包上架两个月做到 20 万安装就算完成任务。本包峰值周增 6.2 万出现在 10-12 那周,之后掉到每周 2 万多;同族最早的 08-14 包周增已经从 5 万多降到 2 万以下。生命周期差不多。

5. Differentiation

No product-level differentiation. Compared with the dozen-plus packages in its family, the only differences are word order in the package name, the developer name and the icon. Compared with licensed platforms like Audiomack, it's lighter and needs no login, but its catalog (if it really is just ccMixter) is far smaller. Its only real "difference" is in distribution: it charts in different countries (Australia, Germany, the Netherlands). That's why it gets recalled in the library, but it isn't a product advantage.

6. How many people have seen it

Hardly anyone knows about it: revenue isn't public, no press coverage, no discussion on X or TikTok; only auto-generated chart pages on AppBrain, Similarweb and Applyra index it (#54 in Applyra's Germany music free chart). But the approach itself is far from scarce: more than a dozen template-based packages already exist, so "copycat" is long saturated.

7. What to borrow

  • The ASO combination of "keyword-heavy tool title + keyword package name + in-app rating prompt + licensed-content source disclaimer" can reliably push a zero-differentiation new package to 200k installs in the gray-area tools category.
  • The matrix play: one developer account per package, package names built from the same set of words in different arrangements, privacy pages mass-generated from a static hosting template, countries allocated, and a new package every two weeks. This spreads the risk of any single package being taken down, and when one reaches end of life, the next replaces it.
  • The player layer is adapted from an open-source local player (mind the GPL obligations), cutting development cost to the minimum and putting all the effort into distribution.
  • These are teams that "eat demand through distribution," not suited to small teams wanting to build a lasting product. If Google cleans up the category, the entire matrix gets hit at once.

8. Still unclear

  • Are they buying installs, and how much did they spend (none of the three ad libraries picked it up); did AU and DE climb to #26 through paid acquisition or organic search ranking.
  • Whether the download source really is only ccMixter, or whether a remote config swapped sources after launch (only indirect hints in the sibling package's reviews).
  • Which open-source project the player was adapted from (APK not unpacked).
  • Whether the packages in the family belong to one operator, or several Vietnamese studios sharing a template or outsourcing vendor (emails and accounts differ; only technical fingerprints like package-name word order, privacy-page templates and disclaimers match).
  • How much ad revenue it makes.
