Thought it was pretty common knowledge that JayZ was the writer of that one ... didn't know he did some of the vocals. Snoop said a few years ago that J wrote that song in about 30 minutes. Crazy that it seems all these genius song writers can just come up with stuff in a matter of minutes.
If you haven't seen it before, I highly recommend going back and watching the show Songland. It's insane how good those people are. They can hear a song in real time and just start coming up with these awesome tweaks. I was extremely sad when they stopped making more episodes.
