Big Sean steps up to the plate as one of the first MCs outside of Drake and Lil Wayne to test the duo's "Used To" track. He surely wont be the last. Sean tackles the track with aggression riding the head-nodding Wundagurl production effortlessly. The OG version of the song first appeared on Lil Wayne's Sorry 4 The Wait 2 and later Drizzy's recent release If You're Reading This, It's Too Late.

Sean's third solo LP, Dark Sky Paradise is slated to hit shelves Feb. 24. Last month he unveiled the track list for the album which will have appearances from Ariana Grande, Lil Wayne, Chris Brown, Kanye West, Drake, Jhene Aiko, PartyNextDoor, E-40 and Ty Dolla $ign. DJ Mustard, Boi-1da, DJ Dahi, Vinylz and DJ Khaled and other provided the beats for the project.
