Re: what UW song should i play at a college semi-formal?!?
 

Yeah, "Jumbo" would probably go over better than anything else. You could also try "Cups," because it starts out nice and easy but then the kids can jump around a little at the end.

"MMM Skyscraper I Love You" might work. People who aren't well-versed in the ways of techno might not get a few parts, but the ending will go over really well, I think. "Dark Train" is very good for dancing, but also not very dissonant, and contains a truly amazing keyboard line, so they might like that.
