It’s not yet, but many think it should be. I know I would kill to have this in Rock Band.
The fact that this song isn’t in Guitar Hero or Rock Band yet is eating away at me, so much so that I actually contacted Stan himself to see if there was anything I could do to help. When he actually answered me I just about died. Turns out not only would he love to have the song in either game, he even contacted Activision himself.
