I have the same opinion on rap. All it does is give some otherwise talentless people a chance to get their 15 minutes of fame.
Of all the other music forms, whether I liked their music or not, at least the musicians were talented.
As an example, not everyone likes Dire Straits, but hey would have to admit that Mark Knopfler is a master guitarist. (Even the "Godfather of Guitarists", Chet Atkins, agrees on that). So far, I've never detected any such talent in the rappers.
Rap seems to thrive on whatever the opposite of talent is.
I decided to change my tag-line for that reason.
