Here’s a fun experiment: think of someone you know fairly to really well, someone you’ve seen dance a decent amount whether it be at a bar/party, in a car on road trips, at karaoke (preferably all of the above), whatever scenario, make a playlist of 5-10 of their favorite bands, and listen to it for an hour or two. You will gain a pretty profound understanding as to why that person moves the way they do. I have done this twice on accident. There is the possibility that everyone already has this kind of insight and I’m just unobservant and obtuse. Obviously punk and metal can be excluded. Nobody needs an understanding as to why someone headbangs or skanks.
