I tried getting a music setup to work, but I couldn't find a good solution for generated playlists with new song recommendations. The self-hosted music service just can't add songs it doesn't have yet, so it's not really feasible. Plus I still have a very cheap YouTube Music subscription from the GPM days.
You can use Lidarr to subscribe to artists’ new album/singles. But you’d still need to have a workflow to add new artists every now and then to incorporate them into your library.
I want to be able to pick a song and say "give me a playlist of similar songs I don't know yet", and have that play immediately. That's just not something a self-hosted setup can do. :/
Yeah I think the closest thing I’m aware of is Plex and album/track mood on smart playlist, and even then that’s kind of janky (ie: cannot shout into smart assistants to creat one on the fly). Music is so cheap now, even the free Amazon Music I get from Prime serves my needs, so I don’t even bother with it.
