I have no proof that these songs are all legit but a picture (that came to my attention via twitter) looks pretty real 
 
Here's a link to the picture (taken from what looks a magazine article)    http://bit.ly/aNHE9U 
  
The songs it mentions are:

Def Leppard - Pour Some Sugar On Me 
Buzzcocks - What Do I Get? 
Children of Bodom - If You Want Peace... Prepare For War 
Kiss - Love Gun 
Slayer - Chemical Warfare 
Queen - Bohemian Rhapsody  
Muse - Uprising 
Metallica & Ozzy Osbourne - Paranoid 
Jane's Addiction - Been Caught Stealing 
Silversun Pickups - There's No Secrets This Year 
Megadeth - Sudden Death 
Dethklok - Bloodlines 
Rammstein - Waidmanns  Heil 
ZZ Top  - Sharp Dressed Man 
AFI - Dancing Through Sunday 
Dragonforce - Fury Of The Storm 
The Cure - Fascination Street 
 
Hell yes @ Bohemian Rhapsody

Too much metal.

thats alot of gay songs

WOOOHOOO- oh wait never mind.

Ok, ok, I'm liking the way that's goin.

Yep, this looks like a Guitar Hero setlist. "Lets go so broad, that nobody will give a damn!" 
 
Although yeah, Bohemian Rhapsody will no doubt be badass.

I only like The Cure and Silversun Pickups from that list... :p And Muse, but not Uprising.

Dethklok? Yes, please.

It's looking like every song will be double bass.. tbh i don't care about this game, rb3 is what i'm after

Oh... wow... one good song... 
 
Sharp Dressed Man. The rest is god-awful other than Paranoid, but who the fuck wants the Metallica + Ozzy version? Plus it's in older GH/RB games. 
 
I am so glad i'm off the music game bandwagon at the moment.

EDIT: Oh ok 2, I didn't see Queen the first time round.

Cool. looks like I won't be missing out on anything

People still play Guitar Hero? I don't think they know that Rock Band has well over 1,000 songs to get from the store now. These yearly updated things are a thing of the past, who needs them when you can get new songs off the Rock Band Store?

Sudden Death isn't a Megadeth song tho

i'll stick with Rock Band thanks

I need to clear my throat in order to express my excitement over this.  Give me a second.
 
*ahem*.... Meh.

Guitar Hero, while I enjoyed 2 and 3, was a little too much on the metal side for my tastes. Looks like 6 is continuing the tradition.

I love metal, but this list bores the fuck out of me

Fuck yeah AFI and the MCR song off Burnout 3. Fuck no to everything else.

Dethklok was the only thing that appealed to me. And even then, it's because I like the group. I think it'll suck to play.

" Too much metal. "

You would have to pay me to play another GH or RB game.

Buzzcocks, Queen, and Muse: YES.
 
Everything else I couldn't see myself being into playing. Guitar Hero still has a lot to learn from the more varied Rock Band soundtracks.

Is Guitar Hero important anymore?

I'd be interested in playing about 85% of that setlist, so that's cool.

More Guitar Hero? Couldn't they just do these as DLC? Or would that just make too much sense?

Wait.... they are making another one?

" Too much metal. "

Great for those who still support Actrivision and the Guitar Hero series. Me, I'm not buying another Activision published product as long as Bobby Kotick is the CEO.

" Too much metal. "

 God, every song on that list sucks, with the exception of Bohemian Rapsody!    

"I love metal, but this list bores the fuck out of me "

I remember when setlists used to get me excited.  Seeing that Rock Band adds roughly two dozen songs each month, I don't really care anymore.

Paranoid and Sharp Dressed Man were already in Guitar Hero games. Seems like they are running out of ideas.
