I think I could use some more All That Remains in Rock Band/Guitar Hero, because Six on GHII was what made me love All That Remains, so they should keep going there. That's my main wish.
Here's a list to keep it professional, though:
The Air That I Breathe - All That Remains
Indictment - All That Remains
Stay Together For The Kids - Blink 182
Killing Cone - Buckethead
Stretching Lighthouse - Buckethead (Alright, any Buckethead will do)
Old School Hollywood - System of a Down
No One Knows - Queens of the Stone Age
Destructo Spin - Between the Buried and Me
Diamonds Aren't Forever - Bring Me The Horizon
A Longer version of Doomsday Arcade Theme - Ian Dorsch... No joke.
Well that's as short as I can make that list, but I'm sure eventually Rock Band and Guitar Hero will eventually satisfy all needs, considering GH makes a new game every year (And it's usually 2-3 games), and Rock Band makes new DLC every week.
