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.
I mostly pirate for others to leech. Always my slsk is getting upwards of 40 users and 30MB/s upload. It is harder and harder to get packs, or music in general from private and not trackers. Redacted does not have everything, I love the idea of big repository of music and share upwards of 50TB on slsk. Lots of Dj's, new producers and podcast use this stuff :) I pay for youtube premium, but never rip it, I almost always buy music I like trough Bandcamp if it is available.
