I have Qobuz and Spotify. There are downloaders for stuff you like enough to archive. I’d probably be happy enough if I didn’t go through my old playlists and find that they just randomly delete shit ALL the time. So stuff I really like, I try to download before it’s gone. Nicotine+ like others have said is probably the most complete you can ask for, but quality can be an issue. The best is private trackers but considering that getting into one is like a full time job, at the point you can’t find something you really want, just buy it or something.
