Amazing. Is there an option to expand the chart and show like all bands with >1M listens for instance ?
This post is self promo spam.
Black Sabbath not being in the middle really bugs me. Also this graph doesn’t have a good time metric.
Whole bunch of awesome bands and then there is deftones.
I managed to find Meshuggah -> Neurosis -> Earth Wind & Fire… something doesnt seem right about those two bands being 2 degrees away…
so you re- launched

fun fact: music-map is ~20 years old.
What exactly are connections? I see starting from tool, no pusifer (maynard), and Deftones, but no RATM,
The UI is also pretty clunky, i wish it expanded out by default, as if you end up clicking on a node you’ve already expanded now it opens their page and if you navigate back you’ve lost your whole tree.
How are edges constructed from “algorithmic similarity”?
Slipknot’s debut was after Korn’s….
What, how is Ozzy “directly” connected to Iron Maiden?
