Just when you thought Guitar Hero III wasn’t going to get any more cool DLC, they drop it on you. Coming Thursday, we get three hard hitting tracks.

The pack will include the heavy lyrics of Flyleaf’s “Tina,” the heartfelt track “Carcinogen Crush” from hardcore-punk turned goth band, AFI, as well as a remix of Marilyn Manson’s grinding, fast-paced “Putting Holes In Happiness” by Nick Zinner from the Yeah Yeah Yeahs.

Hot shit. I’m all over this one. I haven’t played Guitar Hero III in a while, and this is definitely a reason to go back. Now I think it’s time to pick up a new GH3 guitar. My old wired one from Guitar Hero II has seen better days….

Here’s the full press release:
