Musicbrainz isn’t a music streaming server though? I’ve used it to tag everything with mood, and bpm, but I’m not aware of any selfhosted music server that utilizes it.

P.S. It seems like you’ve responded to this post 3 other times.

I’ve used Plex, Jellyfin, and Navidrome. I’m currently using Navidrome, but Plexamp is a massively better product for discovering/interacting with your library. The sonic analysis really takes it to another level.
