This came out early in the latest Rock Band 'zine:

"Alice Cooper Pack:
Billion Dollar Babies (Live)
I'm Eighteen (Live)
Poison
School's Out (Live)
Under My Wheels (Live)
Vengeance Is Mine

The live versions are taken from his performance in Birmingham, UK in 1989, which has previously been released on VHS and DVD as "Alice Cooper Trashes The World", and on CD as part of the "Classicks" best-of collection.

Taking Back Sunday Pack:
Liar (It Takes One To Know One)
Makedamnsure
What's It Feel Like To Be A Ghost? "

I have a bunch of live Alice Cooper in my library; I'm pretty sure they're the same recordings that Harmonix is using.  If so, they're pretty solid.  I've been wanting Schools Out for a while.  I've heard of, but can't say I've ever actually heard, Taking Back Sunday.  I highly doubt I'll get these songs unless they're a buck.  I'm not holding my breath on that one.

I listened to the live versions of the Cooper songs, and they are pretty good. Though School's Out is really different from the original in my opinion. Probably picking up the Alice Cooper songs, I'll look into the Taking Back Sunday songs since they are half-decent in my eyes.

I wish Rock Band 2 were still popular round my neck of the woods because that Taking Back Sunday pack is badass.

Nice, there's always room for jello and Alice Cooper, imo. 

Alice Cooper is pretty great. I remember how "I'm Eighteen" was a pretty good song until Sean Kingston totally decimated it.

sweeet :) alice cooper AND tbs? im sold

Nice, I'll go for the Alice Cooper.

Liar would be a pretty cool song to play.

I'm still baffled why Alice Cooper isn't in the Rock and Roll Hall of Fame, yet music groups that I wouldn't even consider rock are in it.

I might have to pick up a couple of these songs.
