the only problem with people who listen to punk is that... many stop listening when they "mainstream". I think that's stupid. I mean, they are selling their music, it's their art, they made it.... why can't they sell it and make money out of it? One good example is Blink-182. So yeah, yeah.... they got really popular, but whether you like it or not, they still play punk (in this case Pop-Punk), and still have some punk "attitude" there.
Same thing goes for the Offspring.
I love all kinds of punk... pop-punk, skate-punk, hardcore-punk, etc... hell I listen to Emo. As long as they have awesome lyrics, nice sound, and a cool attitude, I will listen to it.
