2. Big Sean – Detroit
As these end of the year lists pop up, you’ll find Big Sean on top of a lot of “Most Improved” lists and this mixtape was exhibit A. Although his debut album, Finally Famous, helmed three hit singles; Detroit might be his most complete work as a solo artist. With no Kanye in sight, Sean stood tall on his own and carried songs like “Mula” with French Montana, “24K Of Gold” with J. Cole and “I’m Gonna Be” with Jhene Aiko.
