Ironically enough, I used to find(and still do sometimes) an awful lot of MP3s of albums on Youtube, the quality of which ended up being substantially better than even some of the equivalent FLACs on Soulseek or Rutracker. This phenomenon reaches a truly comical scale when we talk about obscure one-album bands from late 60s or some early folk tapes, because most of the times YT is the ONLY place on the whole Internet you can find this stuff on, and the users who upload it usualy keep their video feeds/playlists more organised than many of the people from the "tracker scene".
Here are some examples:

It's actually crazy how much information you can pull out of channels like these. And the best thing is: there are hundreds of them littered across the site, just waiting for you to find and download the crap out of them! If you only knew how much dopamine pumps through my brain when I come across another channel of this type, randomly hiding in plain sight. Literally feel like a piligrim, whose pick has finally stumbled upon a large chunk of gold. Using Youtube for music is actually fun and not cringe at all, it feels like treasure hunting more than anything else. Try it as well, you'll like it!
