This is "BeatQuake," a video that shows how often the top 3 songs are played each day over a 90-day period on Facebook across the continental United States. The map is part of Facebook Stories, a blog that highlights different ways people use the social network.
Each song is represented by an individual color. The map's color-coded layers rise and fall as one song overtakes another in popularity. While there is no sound accompanying the video, programmers have incorporated characteristics of each song into the map. Can you identify what that characteristic is?
Some other highlights to spot:
"Scream & Shout" by Will.i.am and Britney Spears goes viral in the South and New York on Feb. 9, around the release of the song's Valentine's Day video.
Macklemore and Ryan Lewis' "Thrift Shop" dominates in New York, Chicago and the West Coast.
"Don't You Worry Child" from Swedish House Mafia has a surge in Texas on Feb. 22.
