18. 21 Savage & Metro Boomin, 'Savage Mode'
On Savage Mode, producer Metro Boomin strips away the fun and whimsy that's come to define much of trap music in the post-Migos world. His empty and brittle framework is highlighted by up-and-coming star 21 Savage, whose rapping style rarely moves beyond a low growl; and, with the exception of love song "Feel It," never shows remorse or regret for the crimes he commits on record. "Nihilistic" is an easy worldview to assign to hip-hop music that sees little hope in the world or in one's circumstances, but few artists reach Savage's level of joylessness. When he raps "That AK-47 turn that smile into a frown" on "Mad High," it comes off not as boast or brag, but as a simple fact. D.T.
