In the fall of 2014, a map of "favorite artists by state" went viral. There was one problem: the map didn't show each state's favorite musician to listen to, but instead showed an artist that each state listened to disproportionately more than other states. The same site later gathered data for a map of the most-played artist in each state, based on music streaming data available through The Echo Nest. Check out a version of the map that shows how certain artists dominate entire regions of the country (check out Jay-Z on the east coast). The rappers, it seems, have taken over.
