I recently set up Sonarr and Radarr on my home server and I'm loving it.
However, I don't get why you would ever use Lidarr. Why would you ever download music using torrents? You can use tools like spotdl and yt-dlp to download songs from YouTube music and Spotify, it's faster and more reliable; I have had some issues finding torrents of music from less-known artists.
To me it seems like it would be much better to have a tool like Lidarr or have support in Jellyseerr to download music from common streaming services.
Convinced that napster was stealing all his moneys and pretty much cemented the idea that people pirating things means you've lost BILLIONS OF REVENUE as opposed to an indicator that you've got a supply chain or pricing problem.
I to this day still make it a point to download anything from them and I refuse to listen to it. If one of their songs comes on anything I'm streaming, I skip.
