A music player for Android that looks and moves like Windows Phone 8's Music + Videos hub.
It plays what is already on the phone. No account, no feed, no recommendations — the library on your device, arranged the way that hub arranged it, and everything that touches the network is optional and switchable off.
minSdk 26 · compileSdk 36 · Kotlin and Compose · GPLv3
Also on the releases page, as an APK — but the two are signed with different keys (F-Droid builds and signs their own from this source), so moving from one to the other means uninstalling first.

The collection is the start screen. The panorama you land on is the library — artists, albums, songs, genres, playlists, history and settings, in whatever order you put them. It is circular, so settings sit one swipe to the left of where you start and nothing is more than a swipe away.
Getting around a big library. Long lists group alphabetically and open the WP8 jump grid over both Latin and Cyrillic. Hold a group header and songs, albums or artists rearrange — by date added, by length, by year, by how often you have played them — and every arrangement keeps headings you can zoom out over, so a list ordered by a number you cannot see still says where you are. Tapping a section header searches inside that section. A long press on any album, artist or genre plays it, queues it after what you already queued, or hides it — and hiding takes effect in every list at once. Album metadata is edited into the tags inside the files, which is the only level where a change sticks. Playlists, favourites, play counts and history are yours and local.
Playing. Media3 in a media session: notification, lock screen, headset and Bluetooth, and playback that outlives the screen. The queue and the current track come back after the app is closed. Apple Lossless is decoded in the app, because Android ships no ALAC decoder and silently plays such files as silence. Equalizer over the device's own bands, sleep timer, and a WP8 volume banner in place of the system panel.
Last.fm. Scrobbling is local-first: a play is written to disk with the second it started and sent when a validated network appears, so an hour underground turns up in the right order rather than as a burst on reconnection. Favourites can be kept the same as your loved tracks, in both directions, as a merge against what the two sides last agreed on. Albums whose files have no cover are asked about once. Lyrics come from Genius with no API token.
CHANGELOG.md is the full list; the reasoning behind the awkward parts is in the comments beside them.
The whole interface is MangoTile, a Compose UI kit for building apps in the WP8 idiom — the panorama and its parallax, the long list and its jump grid, the tiles, the flat typography, the transitions. MetroMusic is its first real application, and every gap this app hit became a feature over there rather than a workaround here.
The framework comes from Maven Central, so a clone builds as it stands:
./gradlew :app:assembleDebug
Last.fm credentials are optional. Copy local.properties.example to local.properties and fill
in LASTFM_API_KEY / LASTFM_API_SECRET if you want scrobbling and cover lookup; without them the app
builds and runs and asks for a key on its own Last.fm page. Get a pair at
https://www.last.fm/api/account/create. Nothing else needs a key.
Release builds are signed with the debug key unless a keystore.properties sits in the project
root (storeFile, storePassword, keyAlias, keyPassword) — installable for sideloading either
way, but publishing needs a keystore of your own. R8 is on. GitHub Actions builds the release APK and
AAB on every push, and attaches them to a release when a v* tag is signed.
