I like almost any type of music or band. I've become quite addicted to pandora radio (www.pandora.com). I type in whatever band I want to listen to and they bring songs from that band and bands that are similar.

but some bands I like to listen to anyways are

lost prophets, lamb of god,
killswitch engage, marilyn manson,
three days grace, 3 doors down,
papa roach, anna nalick,
hatebreed, buckcherry,
underoath, within temptation,
paramore, red jumpsuit apparatus,
red hot chili peppers, hellogoodbye,
linkin park, mae, metallica,
black sabbath, ozzy, slayer,
rise against, the used,
wired, yellowcard,
avenged sevenfold, my chemical romance,
boys like girls
