Grammy-nominated rhyme-slinger B.o.B celebrated his 23rd birthday on Nov. 15 by giving his fans a special gift -- a new song called '5 on the Kush' featuring Big K.R.I.T. and Bun B. The song is from Bob's upcoming mixtape 'EPIC' (Every Play Is Crucial).

Over a joyous trumpet sample from The Impressions' song 'We Must Be in Love,' the birthday boy, Bun B and K.R.I.T. talk about driving in their drop tops, smoking good kush and having hot girls in the passenger seat. B.o.B raps: "My seats all leather / My jackets all leather / Got PETA pissed off cause my pillow full of feathers / Since day one I stay down like a celler / Bun B, KRIT, B.o.B we some f---in' trendsetters."

After listening to '5 on the Kush,' it seems as if Bobby Ray is keeping it in the streets and moving away from his pop-oriented sound. His previously released songs like 'Epic' and 'Strange Clouds' are the hardest tracks we have ever heard from him, so far. B.o.B.'s second effort 'Strange Clouds' is slated to drop in March 2012.
