I saw this link today on Daily Candy, and I got quite a kick out of it. It's a poster called Grand Taxonomy of Rap Names from the company Pop Chart Lab.
It includes such jewels as Doodlebug, Lateef the Truthspeaker, and Krust. If you click the link, you can roll over the image for a magnified view. Be sure to look for categories like Familial, Virtues, and Audacious Misspelling. I know some of my fellow children of the 90s will appreciate this as well.
At 20 bones, I'd say it's a flippin' steeeeel, yo. Yeah. I took it there. What?
