Does all Kanye West do is sample?

Tweet

I have been thinking about this lately. Many and when i mean many i mean nearly all of Kanye West's songs sample somebody else. I mean dont get me wrong hes a great rapper but i believe that he samples a lot more often than other artists. Lets think about it Homecoming- Chris Martin Goldigger- Jamie Foxx Touch The Sky- (That jazz tune cant remember) Stronger-Daft Punk What do you guys think? -Sawyer
