22. Bun B on Killer Mike's "Big Beast"
Bun B is one of the most dependable go-to guest MCs in the game. But even by his high standards, Bun's work on "Big Beast" is remarkable. In the space of 16 bars he takes us from getting schooled to the G-code "a very young age" to the stresses that come with running the block. "A hater wanna catch you slipping," he raps. "Try to be a Jordan, but settle for a Pippen." T.I. also turns in a hot feature on this record, but Bun's is the one. You can't even argue with a verse that ends like this: "Player, I ain't even tripping, but I don't really care/Cause my pistol's in your face, so put your hands in the air."
