A free, open-core mobile and desktop music player that ingests local audio files and provides automatic metadata tagging, album art fetching, lyrics sync, and mood/genre-based smart playlists — all within a clean, streaming-app-quality UI^?. An optional lightweight self-hosted or cloud sync layer enables selective on-demand file sync across devices, so only frequently played tracks are stored locally. A premium tier unlocks advanced features like listening statistics, broken tag repair, and cross-device library management.

Spotify's aggressive ad increases and subscription price hikes are driving a measurable wave of users back to locally-owned music libraries, while mature open-source audio stacks (ExoPlayer, FFmpeg, MusicBrainz APIs^?) now make it feasible to build a polished, feature-rich player at low cost. Growing awareness of data privacy and digital ownership is also fueling demand for self-hosted and offline-first alternatives.
