Why the heck do they use Velvet Revolver in the Guitar Hero

If it’s not in the game?

I saw the commercial yesterday where Slash kills a guy, eats all of his insides and then wears his skin in order to trick somebody into playing Guitar Hero with him.

They used the song “Slither” by Velvet Revolver as the song he was “playing” in the game.

I’m not a HUGE fan of VR, but I wouldn’t mind that song as a track in the game…and it’s not currently unlockable on any of the three versions out now.

I’m guessing it’ll be part of early downloadable content, or something…
