Personally, I've nothing against "Rap" per se. It's generally RapPERS and the subject matter of the so called rap music. Ego stroking and the whole "gangsta" thing is just .... well I can't say what I wanna say without no doubt insulting someone - but needless to say I'm sure you understand my point.
Rapping itself is fine imho, I enjoy Linkin Park, Run DMC, Rage Against the Machine.
