Usher - "Pumped Up Kicks" (Foster The People Cover) 

Usher plays[1] [some] bass.

Good to know.

By the way, while this song is totes uplifting musically speaking, it is a complete downer lyrically.

  1. Who am I to judge, but, judging by his left hand position and his finger style, I’d venture to guess that bass guitar is nothing more than an occasional musical interest of his. But I could be wrong.
