Punk, Metal and Alternative are my favorite. Billy Talent, Stone Temple Pilots, Red Hot Chili Peppers, Disturbed and Godsmack are my top faves. Others that fill up my Ipod are The Clash, Rammstein, The Black Keys, Sex Pistols, Violent Femmes, Seether, Rancid, Shinedown, Jane's Addiction, Against Me, The Bravery, Rage Against the Machine, Black Sabbath, Ozzy, White Zombie, Alice In Chains, Soundgarden, Marilyn Manson, Ministry, Thornley, Beastie Boys, Korn, Arcade Fire, Alexis On Fire....just to name a few.
I like Metallica's old stuff. Ever since Reload came out, I haven't been much of a fan of what they've put out.
