Crossonic Server

OpenSubsonic compatible music server with additional extensions for Crossonic.

Status

This project is in development. Expect bugs and missing features.

Not all OpenSubsonic endpoints have been implemented yet (status). This server implements all endpoints needed for the Crossonic app but may not work with other Subsonic media players.

Features

• Full scan of media library (kind of slow currently)
• Incremental library scan
• ListenBrainz scrobbling
• Multiple users
• transcoding and caching
  • configurable with format= and maxBitRate= parameters
  • raw, mp3, opus, vorbis, aac
• Fetch artist images from last.fm
• Multiple artists, album artists, genres
• Stores a unique ID in the metadata of all media files to preserve IDs when moving/renaming files on disk
• Scrobbling including playback duration
• Browse by tags
  • browsing by folders not supported
• Favorites/rating
• Lyrics
  • unsynced
  • synced
• playlists
  • including user-changable playlist covers (not natively supported by OpenSubsonic)
• SONOS casting (very buggy, not documented)
• Serve Crossonic
• Admin CLI
• Admin web interface
