I'm on 3 different private trackers and they're great for shows and movies. Not so much for music.
To be clear, I'm unambiguously NOT interested in inviting anyone to the private trackers which I have invites for because that is explicitly against the rules and I always follow all rules to the letter. Feel free to private message me. Or message me on Signal
I have pretty good luck with usenet and lidarr. That is if you have some decent indexers. I usually find flac rips fairly easily. I realize that's not torrent and it probably doesn't help you much but I thought I'd throw that out there
