10. Kendrick Lamar, 'To Pimp a Butterfly'
The most politically-charged release of the year, Kendrick Lamar's To Pimp a Butterfly served as the music world's conscience. For the LP, the Compton-raised rapper went old-school, fusing funk and soul samples into his music as well as guest spots from artists like George Clinton, Thundercat, Snoop Dogg and Ronald Isley. The final product is not only one of the year's most musically consistent releases but also one of its most lyrically powerful as Lamar grapples with his growing fame within a climate growing tense with racial injustice.
