there are still people who think rap and hiphop are different styles of music....jeez.
Hiphop is the culture. Rap is the art of rapping and PART of the hiphop culture. there is no "real" hip hop sound and no "real" rap sound. You just have the different styles like lets say dirty south, NYC style, boom bap and so on. but its ALL hiphop and its ALL rap
Hope this helps
