If you are a real music enthusiast then I'd recommend you to join Private Trackers for Music, REDacted (RED) and OrPheuS (OPS) are the two big ones. RED is pretty much the successor of What cd. You'd be able to find pretty much all the music you could ask for on RED/OPS and in the highest quality (FLAC). To join them, you'd have to attend their interview (text based) on their IRC. They'd ask you basic questions about music and bittorrent. You can find more information here - https://interviewfor.red/en/index.html
I'm just warning you, Do NOT, under any circumstance, visit their site while the interview is going on (i.e. while they're asking you questions), they monitor all the traffic coming on that site and if you're caught, you'd be banned from all the major private trackers forever. Don't stress it, all the information they're gonna ask is on the interview site, read it a couple of times and then queue for the interview, getting the interview is the hard part as the interviewers are voluntary members of RED so there are not many of them. Most of the interview happen on the weekends but you would need to queue in a few days ago to get a good position in the queue.
