I'm not really sure what would be best... Last dance, hands down, the best song I played, or what seemed like people liked most, was Scooter - One. I played Fire too, and it went better then the 20 souja boy songs my friend picked... So something like One would be good. I'll go look into those other artists too though.
What is Love is always a popular song too...
Scooter- One(always hardcore) was so good at the dance a couple months ago, some kids requested it again, and 30 seconds into it, some other kid passed out.
