if you like house, breaks, techno, ambient, drum'n'bass or hip-hop, anyways. . . .
i recently started using MPIII.com, and i love it. . . everything they have is live dj sets, no commercial recordings that are available for sale anywhere-- within that spectrum, they have a fantastic selection. . . the downloads aren't exactly free-- they make you "earn" points-- but it's extremely easy and requires very little effort. . . you get five for setting up a profile, and another every time you rate a set that you've listened to. . . so, essentially free. . .
i don't know about most of you rockers, but guys like AWIK, thnikka and hoes should really check this site out-- they've got some killer stuff! if you're going to sign up, do so through my referral page . . .
