We can all agree that Big Sean had a phenomenal year in 2015. From platinum singles to an exceptional album, performing across the world, and delivering one of the greatest homecoming shows ever, he has solidified himself as a force to be reckoned with in the near future. Today, he closes out 2015 with a track fittingly titled 'What A Year' which features Pharrell Williams and Detail. Expect 2016 to be even bigger and better for Sean. Take a listen to this joint above.
