17. Lil Uzi Vert, "XO Tour Llif3"
It says something about this dreary year that one of its defining successes was a numb, drugged-out emo-rap sulkathon centered on the lines "Push me to the edge/All my friends are dead." Then again, Lil Uzi's insouciant delivery guarantees that you can't help singing along by the time the chorus hits. As Sinatra once said, that's llif3!
