music streaming server / free-software subsonic server API implementation

Features:

• browsing by folder (keeping your full tree intact) see here
• browsing by tags (using taglib – supports mp3, opus, flac, ape, m4a, wav, etc.)
• on-the-fly audio transcoding and caching (requires ffmpeg) (thank you spijet)
• subsonic jukebox mode, for gapless server-side audio playback instead of streaming (thank you lxea)
• support for podcasts (thank you lxea)
• pretty fast scanning (with my library of ~50k tracks, initial scan takes about 10m, and about 6s after incrementally)
• multiple users, each with their own transcoding preferences, playlists, top tracks, top artists, etc.
• last.fm scrobbling
• listenbrainz scrobbling (thank you spezifisch, lxea)
• artist similarities and biographies from the last.fm api
• support for multi valued tags like albumartists and genres (see more)
• a web interface for configuration (set up last.fm, manage users, start scans, etc.)
• support for the album-artist tag, to not clutter your artist list with compilation album appearances
• written in go, so lightweight and suitable for a raspberry pi, etc. (see ARM images below)
• newer salt and token auth
• tested on airsonic-refix, amperfy, symfonium, dsub, jamstash, music-assistant, subsonic.el, sublime music, soundwaves, stmp, termsonic, tempus, strawberry, and ultrasonic
