From recognizable forms such as trap and dubstep to the (potentially made up) more nebulous genres like deathstep and heaven trap, bass music is on the rise. While it may not have its hooks into popular culture the way that more established genres like house and trance do, if you've spent any time at dance shows over the past few years, you'll have noticed more and more bass music.
Teens and young adults love the stuff. This is no surprise, as the current generation is one of the first that has known rap music their entire life. Rap isn't edgy or foreign anymore; if it's good enough for Tim McGraw, it's good enough for Middle America.
