Rap died with 2pac and has not evolved past the 90's era. All Eyez On Me was the height of rap, and the genre has only seen a downward trajectory since. It peaked in 96, and has yet to be topped. It is the most stagnant genre on the radio next to country but fortunately, it's on the come up with the new class.
American rock pales to UK rock.
Electronic is the best genre going right now.
The only good Soundgarden song is Black Hole Sun.
Grunge sucks.
