So Blink-182 is a form of speeded up metal? LOL.
Yes, sadly. But to just show you how Blink-182 and other Pop-"Punk" bands came to be:
Lets just start with Blues+ Country = Rock n'Roll + Increasing Complexity = Rock + Distortion = Hard Rock + Increasing length and Complexity = Metal + MORE SPEEDZ!!! = Punk + Electronics = Post Punk(also Proto- Industrial ); Punk + EVEN MOAR SPEEDZ!!!= Hardcore; Punk + Metal = Speed/Thrash Metal; Hardcore + Death Metal = Post Hardcore; Punk + conformity to the Mainstream = Pop-Punk. Plus
dozens of other genres.
If there are any glaring problems someone(Not BRTD) please correct me.
