The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 2.81 MB, so it installs quickly even on modest connections.
This build is signed by "Andreas Kromke" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

Instead of "Artists" and "Songs" in pop(ular) music, this program uses the metadata composer and grouping to organise the music in works (e.g. a symphony) consisting of movements (parts of this work).

Further, no text is truncated, i.e. long movement names or performer lists will take as much space on the screen as they need to be visible in full length.

This application might be seen as an advanced version of the Unpopular Music Player, with added music database query functionality and further enhancements.

The program can work together with the Classical Music Tagger and the Classical Music Scanner.

Features:

* Starts with album list and cover art.
* Nowhere text is truncated (with "..."), even the longest work and movement descriptions get the space they need.
* Composer and grouping (work, movements)
* Views: albums, composers, works, genres, performers, folders
* Filter for combinations of composer, genre etc.
* Text search
* Play lists
* "gapless" playback (as far as supported by Android)
* If configured, uses database built by Classical Music Scanner, otherwise the system database.
* Call Classical Music Tagger or Classical Music Scanner directly from app
* Meta data transferred via Bluetooth to car radio
* Six colour themes
* Scalable UI, also for tablets
* Portrait and landscape orientation
* Perfect gendering-ism, especially designed for useresses and users from German civil service.
