This dance anthem is built around an annoying chant that is abandoned about three-fourths in. Just before it ends, the music, starting at about the five-minute mark, makes its grand transformation into a 1970s-style disco floater to which Justin Timberlake adds a beautiful harmonized falsetto chorus. “All night long,” it goes. That coda, when the groove finally does get in, is exhilarating. It’s a damn shame the whole song doesn’t sound like that.
