37. 2 Chainz, 'Collegrove'
Part Lil Wayne collaboration, part Lil Wayne tribute, Collegrove sees both 2 Chainz and Weezy at their most nimble and technically bonkers. The rappers combined the names of their places of origin – New Orleans neighborhood Hollygrove and College Park, Georgia – and honor their roots throughout, fusing the sounds of the Southern cities as Chainz pays his respects to Wayne's continuous influence on hip-hop and his own career. "If it wasn't for Wayne, it wouldn't be/A lot of dudes in the game, including me" he raps on opening track "Dedication," a song named for Wayne's acclaimed mixtape series. Later, the pair go rhyme-for-rhyme on the energetic "Bounce" and 2 Chainz shines on the solo hit "Watch Out" above an infectious piano riff. B.S.
