What do you mean?   Justin Bieber’s new Skrillex-produced single, “What Do You Mean?”, blindsided many detractors due to its relative quality. In fact, it’s so good it even made Bieber himself break down in tears. But after that emotional VMAs appearance, the Biebs dried his baby blues and appeared on Fallon for only his second-ever performance of the track.

The song was elevated even higher thanks to having The Roots on hand to provide the backing track. What’s more, Black Thought stepped forward to deliver a verse of his own, essentially turning the performance into a remix.
