surprisingly no..i haven't listened to them. an whats scary is people say 'NO ONE WILL EMEMBER THESE GUYS NEXT YEAR I HAVE HEARD THEIR SONGS 1000JUILLION TIMES!' ad i have NEVER heard one of their songs all the way through. from the parts i've heard they sound pretty good. next time i get itunes money i need to buy a few of their songs.
Personally, I don't like them, but I've only heard one song. Some artists, when you've heard one of their songs, you've heard them all. I'm not going to judge them 'cause I don't know.
