Snap Ya Fingers! by Lil Jon. It's a song I actually like stuck in my head. One of the few Lil Jon songs I can actually stomach. I don't care what anyone says, that song is the ish!
It's Going Down by Yung Joc. I HATE Yung Joc, and this song is so stupid. But the Black in me can't resist the beat

. Whenever I hear this song, I instantly think of Tom Cruise getting down on 106th & Park. Yes, Tom was dancing to this song on live television.
Me & You by Cassie. It's such a simple beat, but a great one. I could care less about Cassie, though. Anyone could've song this song, and then some.
