Metal fans rejoice, Dethklok, stars of [adult swim]'s Metalocalypse, will be featured in Guitar Hero II -- bringing them one step closer to world domination. Let us be the first to say, that's effing metal. The song to be featured in the game is called "Thunderhorse," and will be an unlockable bonus track.
In other news, Guitar Hero II will also feature the Trogdor theme from Homestar Runner as a bonus track. If you're unfamiliar with Homestar Runner, you can check out the cartoon that inspired the song here. We've embedded videos of "Thunderhorse" and the Trogdor theme after the break. As if all that weren't enough, we also have the entire track list, bonus tracks and all, to share with you.
