I stumbled upon Troi. Troi can generate music recommendations https://github.com/metabrainz/troi-recommendation-playground
There’s also a playlist generator https://listenbrainz.org/explore/lb-radio/ try it with “tag:edm” or “tag:rock”.
It needs to be integrated into available services and mature a bit but then it can become a spotify replacement. It needs more users for more scrobbles as well. This is awesome! Imagine having automated playlists in a subsonic server based on public popularity.
Such info was usually only available to companies like spotify. This is amazing.
Yes, you can point to the subsonic database of your server instead of a directory with troi cli.
