Hardcore is a subgenre of punk rock that is thicker, heavier and faster than regular punk. It is not a type of Metal, Techno, or Rap. Hardcore is mostly confused with Metalcore/Melodic Metalcore bands such as Hatebreed or Bring Me The Horizon or hardcore techno. The
-core prefix was originally short for Hardcore but now is a random suffix added to anything to make it look more interesting (
Easycore,
Sadcore etc.). It was invented by L.A. bands like The Germs and Negative Trend in 1976 - 1977 and the bands almost never reached mainstream popularity or even wanted it.
