Beautiful cover of Major Lazer’s anthem in a 70’s Stevie Wonder fashion (no, he’s not performing it himself). The guys go by the name of Postmodern Jukebox. Check out their YouTube channel for a series of cover songs including Single Ladies and the likes.
Also check them out on the internets: Postmodern Jukebox
Bonus
Here’s a video of Stevie Wonder doing some carpool karaoke with James Cordon.
