I have recently thought about this quite a lot, why can't rap ever be on "Best song of the year" or "Best album of the year" I mean, grammy awards are categorized by music genres, but except for the categories they also have a few 'general' awards that may be granted to music of all genres (Record of the year, song of the year, album of the year, best new artist) and yet I've never seen any of them given to rap music, never saw "song of the year" winner or at least nominee that was a rap song, same goes with all other 'general' awards.
Perhaps there was in the past a nominee/winner of one of these awards who was a rapper?
What are your opinions about it?
