I don’t think there is anything, really.
Radarr and Sonarr work because the naming conventions for videos are more or less established.
With music, everyone has a different philosophy for tagging, renaming files, transcoding, how to handle best-of albums, compilations, etc. So what works for you probably doesn’t work for me and vice versa.
Lidarr gets very few updates, I don’t think anyone is working on it anymore. I remember the problem was keeping up with metadata handling.

I use tubifarry, a lidarr plugin to use slskd (soulseek) to find and download albums. For me is way better than searching for torrents
