Let me break it down: For me, Crunk & Reggeaton are sequels of Rap ( So they cant become bigger anway, since theyr a part of it). But even if they would be music styles on theyr own, they wont become bigger than Hip Hop. Why? Simple, Hip Hop has a movement, Hip Hop has allot of sides. Hip Hop has meaningless stuff to shake your ass, but Hip Hop also has stuff that makes you think. Thats why it`s so big, caus it can reach everyone. Reggeaton doesnt have that, at least it doesnt have that yet. It`s just to have a good time a party, and if you ask me; Its pretty nice to dance too sometimes. But caus ts only mad for that, I wont grow ut like Hip Hop. It only can become as big as Dancehall or Trance, but I also doubt that.
