Thanks to Kanye West, former Playaz Circle member 2 Chainz has gone from underground ATL rapper to G.O.O.D. Music staple, and now the former is even guest spotting for the latter. 2 Chainz is set to drop his debut LP Based On A T.R.U. Story on August 14th, and "Birthday Song" is the first of three promotional singles for the album. With Ye dropping a verse, even providing production duties with help from Sonny Digital, this is a good sign of what is to come from 2 Chainz's debut release.
The next promotional singles will be released on July 31st and August 7th.
