Right! This is my plan as well. Recently cancelled my apple music subscription, wrote down all my artists. Will slowly restart my collection. Did you mostly torrent?

I use soulseek mostly. As well as these if I can't find it on soulseek:
https://free-mp3-download.net/
When all else fails, yt-dlp. I don't torrent much music because they're mostly private trackers nowadays.
I download flacs and reencode them myself to 320 mp3. I don't have hi-fi equipment, so mp3 is just fine for me.
