That song at the end of the 2011 MTV Movie Awards and some other songs?

If any of you saw the end of the 2011 MTV Movie Awards when they were rolling the credits, you might know the answer. So with that being said, what was the name of the song they played at the end of the show when they showed the credits? Also, What was that song they played when Sandra Bullock went up on the stage to accept the MTV Generation Award at last year's show? There's probably some clips of it floating around on YouTube or you can Google for some videos of it (If it helps at all). One last thing, what's the name of the theme song to that show "Cold Case"? If you happen to know any of those songs and what they're called, that would be great.
