A Guitar Hero Thought

I think that Red Octane (Makers of Guitar Hero) should make a Guitar Hero Dragonforce, Rise Against, Black Sabbath/ Ozzy, Disturbed, System of a Down, Slipknot, and Avenged Sevenfold. Linkin Park would probably too easy except for a few songs. Maybe they should make a Guitar Hero where you can plug in you iPod and play songs from there. That would be just too fun.
