I use Kazaa and I've found loads of stuff I'd never hear anywhere else;

Alkaemy, Ambeon, Chris Squire, Gandalf, Lunascape, Merlin Mystery, Steve Hackett, Collide, Kidney Thieves and Blackmore's Night to name a few.

I found "If Only" by DB on Kazaa. I've used Limewire too but Kazaa is much better.
