First and foremost, personally I've always only preferred rap when it's fused with alternative rock elements, like Rage Against The Machine.
Second, I absolutely hate rap and hiphop shit that carries the usual lame shit: Reversed cap, jersey shirts, baggy pants, gold jewelleries and glorification of crime on the basis that everyone else in their 'hood' is doing it(also fake or artificial tans to make them look more nigga-ish for non Africans). This, or just endless rambling about how much you wanna tap some bitch's ass. Yes, in this prospect, I think the later days of Will Smith in his rapping is infinitely better than the insecure posers we see on MTV every week.
Third, I've yet to find Japanese rap and hiphop acts that doesn't try to do any of the above. Not that I LOOK for it anyway since rap isn't my most favorite, but if you can show me, I'd appreciate it.
