I'd love to leave streaming services and roll my own server, but I rely on things like the Release Radar and song radios for discovery and just haven't been able to find a self-hosted solution for that.
I don't want to have to plan out the music I'm going to listen to, I just want to dive in.
I use the Spotify data via Every Noise at Once (https://everynoise.com/research.cgi?mode=name&name=) to gather band suggestions, but it is an annoying amount of work compared to having a script that sees all of my music and makes a playlist of 20+ songs using that data for me. Have not found a solution for that.
