Pop Punk Rock Retro (Sorta)

Does anyone remember years ago when bands like "Sum41" and "The Strokes" were all over the radio and airwaves in general. (and no The Strokes aren't pop punk.)

But so many people refused to listen to them, claiming they were too mainstream.

I just came across an old song from Treble Charger, and I remember I used to recommend this song to people that secretly liked popPunkrock, but didn't want to show off how mainstream they really were.

How poppy is too poppy?
(Not a serious question)
