Offline Music is a GPL-3.0 Android player based on ArchiveTune. It opens your
local library and searches downloaded songs by title, artist, album, saved
lyrics and available source keywords. Offline playback, shuffle and search
were tested with Android internet permission disabled.

Played online tracks are automatically queued for download by default.
Album and playlist actions save missing tracks directly from collection pages.
Artist Top Songs downloads depend on YouTube exposing its top-song list.
Lyrics and source metadata saving have independent switches, enabled by
default. Source keywords vary in quality and coverage.

Version 0.5.0 adds Open to the Mini widget beside Play/Pause and Next.
Widget and notification playback restore the saved queue before starting.
Compact screens wrap collection actions and keep controls reachable.
Never play again removes unwanted songs or albums from app-managed downloads,
favorites and local playlists, and skips them in queues. Original local
files remain. Download request history survives interruptions, and ZIP
backups include saved audio and metadata with validated import. A separate
Local APK plays files entirely offline. Android may defer download recovery.
Download alerts require notification permission.
