I need ideas for dance songs?

I'm in 8th grade and on my school's cheer leading squad. Well I'm actually the mascot along with another girl, which is fun because we are basically cheerleaders and do everything that they do but we get to dress however we want and have none of the burdens that they have. Back to the point, We have two basketball tournaments every year (one for the boys and one for the girls) between our school and our rival school. At each tournament the cheerleader sand the mascot (two this year) do cheers, stomps, and a big dance number. Right now we are preparing for the girl's tournament in May, and we are still deciding what two songs ot remix for our dance number. We already have decided to do Blah Blah Blah by Ke$ha and 3OH!3, but we need another song. My friend and I have thought up some ideas like shut up and drive, and don't stop the music by Rihanna, and Hot Mess. Do you have any other song ideas that we can dance to? Kind of fast tempo? I'm good with any dance, since I'm an almost professional, but some of the cheerleaders have no experience at all. Thanks!!!
