Atlanta rapper 2 Chainz released 'ColleGrove,' a collaboration with Lil Wayne. The album, rife with clever wordplay, has received critical acclaim since it debuted at number four in the sales charts last month. 2 Chainz described the teamwork between him and Lil Wayne while making the album, stating, "It's built just like you heard it, man. He went, I went, he went, I went, I suggested the hook, he went, I went, I put the hook back in, and I left, like stop. He will rap for 20 minutes.
