Blink-182 wouldn't be where they are today if it wasn't for Green Day, the Offspring, and Rancid charting in top 40 pop radio first. Then the 80's hardcore- Minor Threat, Black Flag, Dead Kennedys, the Misfits. Fugazi, Sick of it All, Earth Crisis, the Dismemberment Plan and anything on Revelation, just to name a few. Blink182 is some kinda southern California punk stuff or something like that. Rancid, NOFX, Guttermouth, Pennywise, Rudimentary Peni, Crass, Less than Jake, Skankin Pickle, Five Iron Frenzy, All, Offspring, Greenday, and bands like that.
Records hates that term.
To me pop-punk seems to just be about having a good time. Getting tatoos and dying your hair is no longer rebellious. It's just another fashion trend.
