Because there's no music in it. Your title is incorrect.
This, for the most part. Rap isn't really singing, and when you compound that with how most rap is about things I can't relate to whatsoever and features terrible backing 'music', you end up with something I'm profoundly uninterested in.
This is not to say I loathe rap universally, I just don't much care for the genre as a rule - there are a few artists/songs here and there that verge into rap or utilize it along with other stylistic forms that I don't mind, and while I don't
love nerdcore I at least find it hilarious.
At the core, I think the reason I don't like it is that it doesn't really
go anywhere - something a great deal of popular music from a plethora of genres is equally guilty of. By not going anywhere I mean that if you were to chart the ebb and flow of the song musically, what you'd get is essentially a straight line from start to finish, a musical landscape devoid of chasms or soaring mountains, something the vocal delivery of rap does nothing to help with. I can't stand club jazz for much the same reason - in my mind, it's a musical journey consisting of running in place for a while.
