So this site is hella interesting. Basically, some dudes wrote up a computer program that sorted a shit ton of music into a shit ton of genres, and then mapped those genres out. Genres further to the top are more mechanical and electronic, while genres closer to the bottom are more organic. To the left of the map is more atmospheric/ambient, to the right is more direct. There's 1382 genres listed so there's a lot to explore.
You can click on a genre to hear an example of it, or click the arrow next to the genre to see a map of bands in that genre. From there you can click on a band to hear a sample of them, or an arrow next to them to see them in spotify. Bands are mapped the same way as genres.
You can also search for a band and it will tell you which genre they are categorized as.
It's hella interesting because it figures it all out based on patterns that occur within individual genres, based on like sound frequencies and shit, and also patterns in song titles.
Anyways, maybe some of you will find this as cool as I do.
