i listen to a lot of screw, and those tapes are just artists songs slowed down and put on cd and resold. was dj screw, and recently cellski, paying for each beat or song they used. i though that if the song was said to be for promotional use they did not need to pay for the use? whats the call on that? on the new cellski mix, which is banging, did he have to pay for the beat on each song?
