Big Sean chucks the deuces to 2015 with the reflective cut "What a Year" featuring Pharrell and Detail. The past 365 saw the Detroit MC scoring his first No. 1 album on the Billboard 200 with his third studio effort Dark Sky Paradise, home to the viral anthems "I Don't Fuck With You" and the Drake-assisted "Blessings." 

"All I gotta say is what a year, what a year," he raps. "I decided now that every year is our year." Pharrell reports for hook duty, singing, "I took my whole life and then I hit the light switch."

Sean Don runs through his highlight reel: performing at Rock In Rio (headlined by Rihanna), selling out shows for a 28-day trek around the globe, and more. He even offers his own New Year's resolution: "This year I'm done with crazy hoes." (The rapper confirmed his breakup with songstress Ariana Grande in April.)

Big Sean also salutes Lil B with the line, "I'm sayin' I'm Lil B with the right wrist." The Based God -- who also released his own project titled Thugged Out Pissed Off -- reciprocated the love via Twitter:
