Eh. There's also a bunch of bozos there that'll literally rip 128 kbps mp3s from youtube and store them as FLACs. I saw it with my own 2 beady eyes right after the release of "The end of you" by Poppy, Amy Lee and Courtney LaPlante. So there's no way of knowing what source they've used.
EDIT: I do like Soulseek a lot tho!
