How many people are lining up for Rocawear sneakers?
I didn't bring up Beethoven, I'm simply arguing that the comparison isn't so far fetched. If you're looking for the Beethoven of rap, you can easily bring up Kanye. I don't know how much historians will look at Kanye, but I can tell you that he's contributed as much to his genre of music as Beethoven.
things move so fast nowadays compared to even 150 years ago. Music is constantly changing big every 20 years. Crazy to think that Snoop or Dre (first big shift) have been in the game for over 20 years when rap is only a little over 30 years old itself. Kanye for a third of all hip-hops life and still very influential expanding it.
