New Vid: 2 Chainz – Birthday Song feat. Kanye West Ms. Bels Friday, August 31, 2012 The Studio Next up, off of 2 Chainz’s “Based On a Tru Story”, is the Birthday Song. The song, which features Kanye West, glorifies 2 Chainz love of big butts. The video is artistically different for 2 Chainz. Maybe some of Kanye West and the DONDRA group’s creative juices were incorporated in the visuals. Nevertheless, it’s a new look for 2 Chainz. It’s good to stretch the imagination from time to time.
