From Listenbrainz website:
ListenBrainz keeps track of music you listen to and provides you with insights into your listening habits. We’re completely open-source and publish our data as open data.
If you use Last.FM, you can import the data into your listenbrainz account. Listenbrainz also has Spotify integration.
It would be cool if Lemmy had some sort of integration with Listenbrainz and last.fm . So users can see what songs others are listening to.
You might look into funkwhale. It’s a fediverse app for music
