What was the song playing in the jeep in the new terminator salvation movie?

So I just went to go see the new Terminator movie and i heard that song but I don't know what its called. Its when the Marcus character first turns the jeep on and that song was playing. He said that it was something that his brother used to listen to when kyle reese asked what was that? Please help me out I would really like to know.|||rooster by alice in chains
