Anyone know this song?

I was watching the DR and Retardz get together video and I love it so much. It's the coolest video. The song makes the video look that much cooler and I have a question, whats the song in it? I cut the part of the song that I thought was cool so you could listen to it and help me figure out the song title or who sings it...

????.mp3

Thanks guys
