Metallica is one of the best bands I have ever heard. I love them. I am going to the Big 4 at the Yankee Stadium this year. Metallica, Slayer, Megadeth, Anthrax. Metal for the fucking win!
I know that one of his songs is from Disturbed... from the album: "The Sickness" I believe... i don't really know. He also used "Uprising" by Muse, and I forget the other songs he used.
