A way to explain it would be that if `` regular hip hop '' was on the middle of a number line , gangsta rap , crunk , and snap would be on one side , and alternative hip hop would be on the other . Even though it is a form of hip hop , fans of alternative hip hop tend to also be fans of alternative rock more than `` regular hip hop '' or especially pop . Alternative hip hop ( also known as alternative rap ) is a sub-genre of hip hop music .
