MusicBrainz makes the list! (via Beets)
I also left a comment on that reddit thread a while back, about using ListenBrainz to save Spotify listening data, which imo is a massive part of Spotify’s hold on people. The sticking point was not being able to import past Spotify history… but I think a few people are working on tools to do that, independently, at the moment!
LB and MB are a big piece of de-centralizing and de-commercialising music
thank you for that reddit link, it help me migrating.
