2 Chainz’s upcoming album, Based On A T.R.U. Story is taking more and more shape. After unveiling the official artwork of the tune a couple of weeks ago, the ATL native now unleashes his collaboration with Kanye West, titled “Birthday Song,” in its full streaming glory. The track, which is also available on iTunes now, will further nourish the rumors if the artist, formerly known as Tity Boi, has indeed joined the G.O.O.D. Music roster. Based On A T.R.U. Story is due August 14.
