Indie means independent right? so it means pretty much any band that releases an album or song independantly without using major record companies. so a rocker could release an album by himself and its Indie. A rapper could then theoretically release an album by himself and he'd technically also be indie. A techno song could be Indie. so could pop, grunge, metal, jazz, etc etc. as long as its released independently.
So why the FUCK do people keep calling it a genre?
Person 1: My favourite genre of music is rap.
Person 2: I hate rap, i loooove Indie though. Especially Atmosphere.
