That's funny, but lets get back on topic. :) If your just starting out you'll more than likely be the opening DJ so don't play any anthems. Your job is to do just like it sounds, warm up the crowd. When you start there will more than likely be few people dancing and that's fine. Your there to get them in the mood, buy some drinks and loosen up. As you progress through your set more and more people will start dancing, but you should probably have it set in your head that you don't want the dance floor packed. That's the headliners job, do this well and you you'll progress up to that headliner spot.
