How about these?

[TheMaimMan]

As far as full albums go, i'd love to see these merely for the fact that they all are good albums (full band-wise) from start to finish:

Days of the New - Days of the New I (Orange)
Megadeth - Countdown To Extinction
Godsmack - Awake
Stone Temple Pilots - Core

And some good single songs or packs could be:

Guns N' Roses pack (Sweet Child 'O Mine, November Rain, Paradise City)
Staind (Mudshovel, It's Been a While, etc)
Audioslave (Cochise, Show Me How To Live, Be Yourself)
Slayer (South of Heaven, Mandatory Suicide, War Ensemble)
Megadeth (Peace Sells, Holy Wars [for those of you who think the game is too easy], Train of Consequences, Trust, Washington Is Next)
System of a Down - Chop Suey, Toxicity, Aerials, Innervision, BYOB, Question!, Hypnotize)
Alice in Chains (Man in the Box, Would?, Them Bones, Rooster, Angry Chair)
Flaw (Only the Strong, Payback, Whole)
Pantera (Cowboys From Hell, Cemetery Gates, I'm Broken, Revolution is My Name, Walk, Goddamn Electric [i know, long-shot due to censorship])

I know, probably all have been asked for already, but I hope someone from the DLC department takes notice ;)
