Which transformers score song plays when Sam takes the cube to the city?

There is this one song that plays during Transformers 1 that i really like but I can't figure out what it is called. It's played when Sam is taking the cube to the city. Please help!|||I think that it's Downtown Battle, but I'm not entirely sure.|||I think it is 21 Guns by Green Day really. I love the movie transformers and the game transformers, so collected some good articles and sites, around 200, for transformers movie and video games.
