The last one was instigated by me, and I participated in the Quomodocumque discussion, but I had nothing to do with the others.  

Or look for more on Twitter or Google+...  

PS: Recent additions include moombahton, c-pop, chinese traditional, chinese indie rock, post-disco, baroque, romantic, classical period, serialism, neue deutsche welle, tekno, gamelan, old-time, tin pan alley and classic garage rock, and improvements to garage rock (which is the modern revival version), death metal and opera.  

I also made some tweaks to the artist-mapping code within genres to cut down on spurious outliers a little, and am trying some hopefully-improved logic for picking the example songs for each genre. And I put a "find artist" widget on the front page, which will tell you which genres that artist is in. Keep in mind that I only show a couple hundred representative artists for each genre, so plenty of bands that we would all agree "are" a certain genre won't actually appear in the maps here.  

You can also now go from an artist to their Rdio page. The "related artists" on Rdio come from the same Echo Nest data that powers the genre maps, so this lets you keep exploring more or less indefinitely.  

And I created a Twitter account for @EveryNoise, which I'll use for minor news and updates, rather than posting every one of them here.
