From the description, this site seems to either be a Spotify research project, or at least powered by Spotify data in some way. It's not clear to me.

Every Noise at Once is an ongoing attempt at an algorithmically-generated, readability-adjusted scatter-plot of the musical genre-space, based on data tracked and analyzed for 6,259 genre-shaped distinctions by Spotify as of 2023-07-12.

Personally, I cancelled my spotify account and moved to a combination of Plex and Tidal, but this project is just too cool not to use.
