An algorithmically-generated scatter-plot of musical genres - with samples (everynoise.com)

I don't get why 'ska punk' is right next to 'contemporary country'.

:) cool.

Has some glitches: go to Grunge (http://everynoise.com/engenremap-grunge.html) and click "Nirvana 2002" :)

This is amazing. While it seems a bit scattershot as far as relationships to other genres (what do the colours mean?), this is a really cool way to discover music. Kudos!
