Big Sean is back! Today the Detroit rapper released a new music video to his “1st Quarter” freestyle. Big Sean goes in, giving all the “Know-It-Alls” a shout out, “Got my rolex at Pacific, while I fly in through the Atlantic and just like a Know-It-All, I always got the upper hand and if I listen to you bitches I would still be on the campus . . . I swear she’s from Atlantis”. You have to listen to it! I wonder what Sean has in store for us in the next three quarters!? I’m sure whatever it is, it’s gonna be -fire -fire -fire! Check out Big Sean’s “1st Quarter” below!
