If you are like me, sometimes you will hear a reference to a type of music and you think "uh"? What IS that? Apparently Glenn McDonald has also wondered that. I do not claim to understand what he has wrought in his "attempt at an algorithmically-generated, readability-adjusted scatter-plot of the musical genre-space, based on data tracked and analyzed for 1436 genres by Spotify".
If you have an interest in exploring the different musical genre's, I recommend a journey to Every Noise at Once .
