4. Jay-Z f/ Kid Cudi "Already Home"
Album: The Blueprint 3
Producer: Kanye West, No I.D., Jeff Bhasker
Cudi seized the moment when asked to be on Jay-Z's last solo album. He comes in on the chorus with the same attitude and passion behind Hov's verses, and the appearance marked a big step forward in his career, gaining Cudi a lot of attention from hip-hop heads who had overlooked him prior to the guest spot.
