I listen to Rock bands like Sum 41, 30 Seconds to Mars, Fit For Rivals, Bush, Guns n' Roses, Foo Fighters, Egypt Central, etc. Post-Hardcore bands like The Devil Wears Prada and Alexisonfire are good too. I like Grunge bands like Nirvana, Pearl Jam, Soundgarden and Alice In Chains But I also love my Metal. From Heavy Metal bands like Metallica (seeing them in November!!), Iron Maiden, Godsmack, etc to some Metalcore such as As I Lay Dying, Killswitch Engage, and Bullet For My Valentine. My favorite metal genre would be Melodic Death Metal though with bands like In Flames, Children of Bodom, Arch Enemy, Amon Amarth, Kalmah, etc. Well that just about covers the type of music, don't really have a favorite though, just depends on what mood I'm in.
