Jimbob131190 please don't be kidding about Zebrahead coming to Rock Band, I'm a fan of them too and would love to see "Falling Apart" and
"Now or Never" on the game. I hope they definitely hop on it right away.
By the way, I've also re-contacted Amorphis. I emailed their manager last time (as far as I know) which I have not got a reply yet, I managed to find the band's email and have contacted them last night. I really hope they consider it, will let you know when or if I receive a reply from them.
