Map of Heavy Metal

I find it interesting that we're on the capita as Australia, Spain and France. Love my country, but we have a complete lack of appreciation for heavy metal music. If it isn't pop or country these days, it doesn't exist.
 
The prevalence of Europe here doesn't surprise me. I wonder what the radio support for metal in the Scandinavian counties is like, because it's been almost non-existent in the states unless you're talking some of the more mainstream bands, many of which wouldn't even qualify as metal to some.
