G.O.O.D. Music's Big Sean stopped by Hard Knock TV for a short freestyle over production from The aUtOMatiKs. While a lot of these on-the-spot freestyles seem pre-planned, it looks like Sean really gets into his zone and goes off the top for this one. Check it out above, and look out for that G.O.O.D. Music compilation coming soon.
