Does it even matter? You think avenged sevenfold is the best band ever, you are clearly doing everything wrong in life. That or you are 16.
So because I enjoy a type of music I am doing something wrong? I am 18, and I work and I'm in school. What I listen to shouldn't mean I am doing something wrong. At least I don't listen to rap which has nothing but profanity in every song. Avenged Sevenfold went a whole album (Waking the Fallen) without using a curse-word.
