Honestly, JB is the only like pop/rock band I listen to. And they've even gotten less poppy with their 3rd album, IMO. But I really love all their music of course.
I'm getting into Paramore, I think bands with female lead singers are really cool. Hayley's got a great voice. I'm not really sure what category they're in.
I love classic rock. I was raised on it. I looove the Beatles, The Who, and Queen, and no, I don't just know 2 songs of theirs. xP
Also, Jimmy Buffet. Yes, my family used to be boat people. xD Jimmy Buffet 24/7. xD I still love listening to him because it just brings back a lot of memories.
I love hearing female singers with really strong voices, like Christina Aguilera. Basically anyone who can sing and give me chills.
Into that mix, throw in Micheal Buble, some Linkin Park and Weezer and that's me. xD Soo random I know, but honestly there isn't really any music I don't like.
