If you feel as if you’ve seen a version of this map before, you probably have: Squint and you may recall a viral map of the places that account for 50 percent of the country’s gross domestic product. Or a map of the counties where Hillary Clinton beat Donald Trump (54 percent of the population, but just 15 percent of the land mass). Justin Timberlake’s fan map is indeed like those in the sense that it is largely a map of American cities. Yet there is a notable exception: Southern cities do not particularly care for J-T. Even his hometown, Memphis, does not burn particularly brightly for him.
