Music used in SYTYCD?

There was a song played tonight that I like, but I dunno who performs it! It was played during the hip hop choreography of round 1 I think. I'm hoping they show who it is at the end of the show because it's driving me crazy!

There are a few spoiler SYTYCD sites that post songs afterwards...I watched them like a HAWK last year, lol! But, at the very least, you can find one and ask in the comments, someone will answer you!

My sister got me hooked on that show tonight! LOL
