Guitar Hero III drops at the end of next month. But if you still haven't gotten enough, Billboard is reporting that a soundtrack album for the game will be released on Oct. 30 (two days after the game). But this is no mere soundtrack. It has been imbued with the power to unlock three additional songs for the game via Xbox Live with an included code. They include "Carcinogen Crush" by AFI, Flyleaf's "Tina" and a remix of Marilyn Manson's "Putting Holes in Happiness" by Nick Zinner of the Yeah Yeah Yeahs fame.
Also included in the announcement is the nugget that Sonic Youth's "Kool Thing" will be included in the game, which is one we haven't heard before. (There's a full list after the break.) As far as we know, there will be no similar code for PS3, but Billboard makes no mention of it, so it seems unlikely.
