For convoluted logistical reasons, the maps on Every Noise at Once haven't been updated in a while. The associated The Sound Of playlists have kept updating every week, but the genre list itself, the artist/genre assignments, and some of the other bits of map infrastructure have been involved in a slow belated technical migration as a result of the acquisition of the Echo Nest by Spotify two years ago.  

But this is all done now, or close enough, and the map is updated and updating again!  

Presumably nobody was really waiting impatiently to find out how many pixels left or right aggrotech should have shifted during this time. Encouragingly, ripping out all the data for the map and replacing it with new data didn't radically change everything. By which I mean, of course, that it initially wrought abject chaos, but after a day or two of frowning at code I wrote a long time ago I got the entropy basically re-contained. Mostly the products of this migration are straightforwardly good, and just magically make everything better. But sometimes the magic fails, and it takes a little human attention to allow the betterness to assert itself properly, so if you notice anything strange, let me know.  

More notably, reactivating the whole system makes it possible to add and remove genres again. A few marginal genres basically got absorbed by the data-fueled expansion of more prominent or interesting things, but mostly the deeper data made it possible to model known things I hadn't been able to include before, and to give names to obscure and/or emerging clusters that our old instruments weren't powerful enough to clearly discern. The net effect takes us to 1435 genres as of today, and these are the new ones:

Some of these, to be clear, although not necessarily the ones you think, I made up. That is, they are names I made up for music and listening modes that I did not make up. Whether this makes them "really" genres is an existential question we can debate while we listen.
