Imagine, if you will, the unadulterated feeling-yourself-ness of Drake in the “Hotline Bling†music video, as infused with some actual, let’s say, physical dexterity. Done dreaming? Good. Let us present Bruno Mars and his music video for “That’s What I Like,†a wondrous three-and-a-half-minute interlude of groove. In it, Bruno Mars dances, and only Bruno Mars dances. He’s accompanied by naught but his own vibe and some silly animation that works to emphasize the cartoonish flexibility of his own exoskeleton. All in all, almost makes up for the lack of the ubiquitous music video cube.
