B.o.B drops his A.I.R. mixtape via DatPiff today (Sept. 1). After dropping Water, F.I.R.E., and E.A.R.T.H earlier this year, Bobby Ray completes the series with his new tape, an acronym for Art Imitates Reality.

The 11-track offering is solely solo cuts from the ATL export. And because he's dropped yet another mixtape around the theme of mother nature's elements, fans can't help but remember B.o.B's claim from earlier this year that the Earth is flat. The Atlanta star caused quite the stir on Twitter about the subject and even led famed astrophysicist Neil deGrasse Tyson to chime in on the matter.

“Innovations in science and technology are the engines of this century’s economy,” Tyson told XXL. “And they are the foundations of our health, our longevity, our security and like I said our wealth. If you are going to breed a generation of people by whatever influence you have power over to not understand what science is and how and why it works, you are undermining our ability to stimulate our health and our wealth and our security."

Astronomical beliefs aside, B.o.B has clearly been putting in work. And although he hasn't dropped an album since last August's Psycadelik Thoughtz, the Grand Hustle/Atlantic signee has enjoyed the success of platinum status this year thanks to the RIAA's new policy of counting a certain number of streams as sales. As of 2016, Bobby Ray has scored plaques for four of his most radio-friendly singles: "Both of Us" (1,000,000), "Nothing On You" featuring Bruno Mars (3,000,000), "Headband" featuring 2 Chainz (2,000,000), "Airplanes" featuring Hayley Williams (5,000,000).
