It was only a matter of time, people.
This is an intensely danceable song, and it's got a catchy chorus. How Justin Timberlake has kept his energy so high for so many years, while allowing his music to both mature and still be fun, is a mystery for the ages.
Also, smart move on the part of the makers of the movie Trolls, out later this year and from which this song is, to release this song in the summer. All they're doing is kicking off their buzz early.
