He's a musician, I'll agree with that.
Timbaland has been successful at sampling house music, but I haven't heard much of an eastern music from him and what are the "other" things?
Eastern music? Electronica? Rock? You're honestly questioning the variety of his sampling?

So what are you arguing - that he is the same as the majority of hip hop producers, because he only "recently" came around to sampling other things? And are we going to discount Late Registration?
Hold on, you didn't even counter my point. Graduation, which is Kanye's most varied album, is still dominated by samples of music "most" hip hop producers dwell on, according to you.
Sure, let's talk about Late Registration, which is even more heavily dominated by the sampling trends of the average, run of the mill hip hop producer according to you.

Your argument has no legs, and constantly moves the goal posts. YES hip hop was built on James Brown samples, no one will deny that. My argument is that sampling techniques changed a lot, not only recently but in the 90s as well.
My argument:Kanye West's production style has evolved from the Blueprint days, sure. But while he has recently branched out with some interesting samples, the majority of them remain deeply rooted in R&B, pop, and soul. Sampling Can and Steely Dan didn't change that on Graduation. His mainstream peers like Timbaland, DJ Toomp, Dr Dre, The Neptunes, Diddy, Swizz Beatz, Scott Storch, etc have all sampled various genres of music as well. He's not an exception to a rule, he's not a pioneer, he's not particularly revolutionary etc.
