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?
I use it. It’s just as easy to set up and run as the other two, whether you use the tarball install, repo packages, or docker. While you’re at it, look into Prowlarr also to manage your indexers and download clients so you don’t have to make changes on all 3 manually. Then maybe look into Ombi to manage download requests. I like Overseer better, but it doesn’t support music yet, unless something changed recently. The biggest hurdle is that in contrast to the TV and Movie categories, the file naming conventions for music downloads are not nearly as well standardized and enforced. Lidarr does a great job of shifting through and finding what it can, but I still get a lot more releases that require manual importing than with Sonarr or Radarr. Maybe I just need to tune the filters better. Discovery isn’t really something Lidarr does yet, although there may be some forks working on adding it. Last.fm or listbtainz can help with that, or there are a bunch of self hosted media trackers that have recommendations built in.
