Incubus would make a great Rock Band addition. 

I think Buckethead would be a suitable Guitar Hero III content package.  With the inclusion of vocals in World Tour, Buckethead as downloadable content defeats part of the accessibility of the game.

In fact, a lot of obscure post-rock goes out the window as microphones waltz through the door.

Caught in a Mosh - Anthrax

Heaven and Hell - Black Sabbath

Bang your Head (Metal Health) - Quiet Riot

and as much TV on the radio as you can cram in

 Forgot about them, at least Wolf Like Me if nothing else - fantastic song!

Master of Puppets by Metallica.

I want some real maiden for Rock band, the covers are terrible.
Bruce Dickenson is just one of those people who simply can't be covered.

Rock Band just needs more indie rock.  Some stuff from Les Savy Fav (Patty Lee), The Walkmen (THE RAT), and My Morning Jacket would work great.
 Most of all this game just needs My Morning Jacket's One Big Holiday.  Seriously it would be perfect.

"Dream Theater!"

What I think Rock Band needs is some more Iron Maiden. Any song will do, I do really like The Trooper though. But if  I can't get that there is Disturbed and Nirvana.

"

NEED MORE STROKES, RHCP AND COHEED :)

Radiohead, R.E.M., more indie rock as suggested by MSG, Kings of Leon could fit nicely i believe....and if ever possible which i highly doubt "while my guitar gently weeps" by the Beatles of course....considering Jimi Hendrix and Led Zep..jsut wont ever happen for Rock Band

Mainly bands that haven't been recognized in DLC yet. Slipknot I've been waiting for for a while now.  Bullet for my Valentine, Trivium, Atreyu, and Mudvayne would all be nice too.
Still waiting for more Muse and Maiden though. Top three requested bands from me would be
1: Maiden
2: Muse
3: Slipknot

Just some Linkin Park or Three Days Grace. Thats all I ask for. Oh, and Back In Black by AC/DC.

BEATLES

The Hold Steady, of course.

"Gimme some Bad Religion and a lot of ska and I'd be happy."

Any Green Day Song would make me happy, but I "Jesus Of Suburbia" would be freakin' amazing! The Whole 9 minutes!!!

I'd really like to see more Radiohead. There are a lot of songs that would be amazing to play. Heck if they just released Ok Computer or In Rainbows I would be very happy. Specifically I would like to see Climbing Up the Walls, or Let Down.

I would also be happy to see more Modest Mouse. They have some songs that could be awesome, but they aren't popular enought so we get stuck with "Float On".  I'm still happy just to see Modest Mouse, but there are a lot better songs by them.

Any song from Lostprophets and I'd cum in my pants. But cool things like that don't happen.

Twisted Sister

"I would like to see some Rage Against the Machine as well, many of the songs would be amazing for drums.
"

Only 1 person said Zeppelin.  Wow.  I would go with them, more Wolfmother, more AC/DC, and more Lynyrd Skynyrd.

Song for the Dead please!

Alice Cooper
Black Keys
Silverchair
Cake
White Stripes

And obviously The Beatles and Led Zeppelin

I'd love to see some Violent Femmes, and I think they'd make a great fit. Awesome drum parts, fun vocals, and sweet walking bass lines FTW!

Blister in the Sun is an obvious "everybody knows that song" choice, but Please do not Go, Prove My Love, Gone Daddy Gone, Ugly... man, how 'bout I just say the whole first album and shut up.

That is all.

"Gimme some Bad Religion and a lot of ska and I'd be happy."

UP THE IRONS!

How about songs from the Throwing Copper album by Live or some Creed would be awesome too.

AC/DC. Most def.

Also I think Ted Leo & the Pharmacists would surprise more than a few people.

Also: Master of Puppets.

Guns N' Roses and Motley Crue packs would be awesome... OLD CRUE!! nothing after the Dr. Feelgood album.  Would also like to see some GWAR!

"The entire Blue Album by Weezer, I gonna keep saying this until I get it.
"

lightning bolt, ok computer by radiohead, some more ludicrous speed metal stuff, death from above 1979. I guess the problem with dfa and the bolt is they are 2 person bands but there must be some way to get around it!

We are Scientists.

System of a Down.

How about some Slipknot or Slayer! Those bands would be great for drums! Also more metallica would be great

"Dream Theater!
"

I wanna say I want more extreme metal type stuff but it would be damn near impossible to play on drums, at least on the drum controller as it exists now. But here goes:

• Metallica - Master of Puppets full album
• some Black Dahlia Murder
• some Pan-fuckin-tera!
• anything by Lamb of God or Slayer
• Pink Floyd's Dark Side of the Moon, Animals, and/or The Wall full albums complete with achievements/trophies for the playing the whole album in one session. Tell me that isn't an awesome idea.
  

I really, REALLY want to see Kings of Leon and besides that...I would like to see some more Muse.

Would love to see THE KILLERS first album released as DLC.

Would love to see some heavier stuff, such as Machine Head, Lamb of God, Korn, Slipknot, Rammstein and so on. I also wouldn't mind some Marilyn Manson songs or System of a Down, that would be sweet.

What I was hoping for was some Alter Bridge or perhaps Pearl Jam. Audioslave is also a welcome addition!

Ac/dc

Muse.  I want more Muse damnit.

any punk and ska will make me happy :D

I want more NIN, Metallica, Radiohead, Queens of the Stone Age, and Rush.

I'm going to get flamed for this but I'd also like to see some Dragonforce. >.>

I'd also like to see some Megadeth (they're going to be in RB 2 after all), Queen, Pink Floyd, and Led Zeppelin. Yes, I know the last two are pretty much impossible.

Oh and I'd actually like to some Chinese Democracy tracks.
