I use Radarr and Sonarr for my movies/shows, and Spotify for music, but I do know there's another *arr app for that. The question is, is it worth setting up and how easy is it to discover new/similar music as opposed to Spotify, given that Spotify isn't expensive at all. And how do you fellow crewmen go about it?
Once I discovered the Ad-Free patch for Spotify I shutdown my Lidarr. Much less hassle, and it freed up a solid 300GB of space on my NAS.
