Pop punk music is usually more melodic and cleaner-sounding than the original punk rock music. Bands such as New Found Glory, Sum 41, Good Charlotte, Yellowcard, Simple Plan and Fall Out Boy have refined pop punk into a form which stresses strong melody and varied rhythms. Lyrics would prety much be the same the only difference would be in the style of singing and also the music. PUNK rockers would tend to sing at a much fatster pace whereas POP-PUNK rockers are melodic and would tend to be slow and much more clearer.

***** One more very important thing, please DONOT listen to all these people in here trying to tell what Pop-Punk genre is all about as most of them donot know shyt about PUNK. They consider Bad Religion & NOFX Pop-Punk. I mean they are the Godfathers of hardcore PUNK ROCK and even a deaf person can tell they are most certainly not POP-PUNK. I had a good laugh when these so called 'smart people' tried to categorize NOFX and Bad Religion into Pop-Punk. Go listen to them first and then decide for yourself.
