Of course, the casual listener not gonna listen to some crazy off the wall stuff until it gets poppy and commercialized, but Rap been at the forefront of all the pop trends of the last decade.
Most of the stuff Indie and Electro been doing the last 10 years is rehash of earlier stuff. Funny cause EDM is just a heavy bite on Southern Trap, 90 RnB, and House. All Black created music but they so "experimental" huh?
Seriously name some experimental Indie or Electro? Bet most of it has been done or is a mash up of different styles of stuff but nothing new.
