Simple, self-hosted music scrobbling database to create personal listening statistics and charts. Doesn't have any of the bells and whistles that sites like last.fm have - no social networks, no recommendations. The data is yours, and it'll remain yours. Can log multiple artists per track. Written in Python 3. You can import your last.fm data if you download it.
Supports both the ListenBrainz and gnu.fm scrobbling protocols, so just about any client you have should work.
Has its own Chrome addon.
