I’m no expert on “pop punk”. I’m sure that there’s some record store owner out there who’s way more knowledgeable than I am when it comes to this genre.
But you can kinda figure out who belongs in the category….
And this list by Loudwire is interesting in the fact that there’s no Offspring or Ramones or Rancid. I’d definitely put “Smash” by the Offspring on here (Bad Habit was THE JAM)
and “Out Comes the Wolves” from Rancid.
Of course, you’ll find Green Day, Blink 182 and Good Charlotte on here, but there definitely seems to be some bands missing.
