I'm pretty sure it was Criminal Minds but then I went here:

And it didn't mention Have A Little Faith in Me at all.
Okay, it's still me Daizelle but I couldn't log in for some reason so now I'm Daizelle22.
Anyway, I found the song!
In case anyone else is wondering it's Shake, Break, Bounce by The Chemical Brothers off their 2005 album Push The Button.
