I think y'all got it wrong, back in the day, the DJ made the beats, and scratched it up. I mean they would take the break part of a beat and loop it with the tables while the mc emceed. Then time went on where they would sample, and make their own beats, but they would throw scratches in cause that was like their solo part [see terminator X it!]. So the deejay was mainly the producer, but now, the dj is mainly a record spinner hype man type. Cause now the producer/dj, can walk on stage and rap too![see the intro for every new song]. Cause if dre does a track for you, he's not gonna go on tour and stand in the back spinnin records for you, your DJ's gonna do that. All the old school cats still get out there, and rep [premier, Jam master Jay (rip), mister Cee], cause thats how it was, and always be. But new cats don't have dj's, or rather "dj nobodies" spinnin and keepin the show goin cause they got multi producers on the album.
