i found that nice clean fast mix's can get the crowd buzzing.....i did a dj comp in Lemington one time, and fited 12 tunes in to 15 mins....and the place loved it,i finished 2nd that night hehe

I try to do it alot(when i used to dj at free partys and clubs) as i have many records i love playing...and people would tell me how good the fast mixxing was. give it a try and see if it helps at all.
