I gave a talk on music discovery and genre-mapping at the 2014 EMP Pop Conference in Seattle last weekend. My co-panelist Michaelangelo Matos had the presence of mind to record the audio from this, and mostly the talk was just audio. Actually, I was wearing some really excellent silver pants, but while talking I was behind a podium, so you aren't missing that much. The map I describe at the end is Every Noise at Once.  

So if you're curious, the talk is 16:32 long, and you can listen here:

And, although this will not make a lot of sense until after you listen to the talk, the playlist I narrate is also available here:
