I found it weird looking at my region and not a single map had any significant shading to it. I wonder if our tastes are just that esoteric or my neighbors prefer a genre of music that isn't represented in this article. Also some of their analysis doesn't quite line up with the graphic... "of course, Eminem is popular in his hometown, Detroit" while Detroit is as darkly shaded on the map as, say, northern New Mexico.
