Sustain

Sustain is an iTunes-style music library and player for Linux. Configure your music folder and it'll manage, rate, search and play your local collection. Basically the iTunes workflow from back when iTunes was actually good.

Most of what you'd expect is here: the dense sortable songs table, the album-art grid, star ratings and play counts, smart playlists, and search that stays fast past 10,000 tracks. Plus a few things iTunes never did : BPM and musical-key detection, duplicate consolidation, CD ripping to FLAC or MP3, and optional backfill of missing tags, artwork and lyrics from MusicBrainz and similar sources.

Syncing isn't iPod-bound. It pushes playlists to a USB stick, SD card or Android phone over MTP, incrementally, the same way you used to sync an iPod (handy for a car head unit). It can also write a proper Pioneer Rekordbox database to a thumb drive (BPM, key, beat grids, waveforms and artwork) so CDJ/XDJ gear reads it natively.

Built in Rust with GTK4 and GStreamer. There is no Electron, no Chromium, cold start around 100ms. Free and open source under GPL-3.0.
