Snoop Dogg's "Eyez Closed" (2011)
Producer: Kanye West, Mike Dean
We already heard pieces of Kanye's verse about a year before it wound up on Doggumentary. He first spit parts of his verse (as well as parts of "Dark Fantasy") in the momentous G.O.O.D Music cypher at the 2010 BET Hip-Hop Awards. Then in January, the track leaked with the Kanye-produced instrumental before the mastered version showed up on Snoop's album in March. Yeezy's verse still sounds just as good the third time around, though.
