I wouldn't be surprised if people on the spectrum were drawn to it. One of the key symptoms is sensitivity to different sensations, and dubstep is one of the few styles of music you can literally feel. When it's done right, you don't just feel the bass in your body, but also in your head. It's actually disorienting. It can be such an intense sensation that I actually find it really enjoyable.
Of course, this is only for real dubstep, when it's done right. Unfortunately, when most people think of the genre they only know manic, annoying BS like Skrillex, where the bass is just midlevel, so it doesn't have the appropriate effect. Fans of the genre have actually come up with a derogatory term for that sort of thing, "brostep."
As far as EDM goes, I like the rave genres (goa, breakbeat, progressive house, DnB). I like the heavy, dark dubstep. But in general, the only electronic genre I've really immersed myself in is the experimental/noisy part of industrial (Test Dept., SPK, Einstürzende Neubauten, Skinny Puppy, Factrix, Ministry).
