The only thing I think I've noticed is that a lot of aspies tend to duck from anything that's got an immersive amount of emotional grime, a really stoned and immersive melody, or a real emotionally reticent melody (aka. kinda anti-climactic and controlled), me I love it. Not to say that lots of NT's aren't into that either but I find more NT's I think who get into that side of things. If I've noticed any aspie trends its been things like nu-metal, rap metal, Weird Al and Frank Zappa, 80's, if its hip hop its the lighter side, and usually almost anyone I met who listened to j-pop and video game music it would be hard to imagine them being anything else (unless they're Japanese - its their culture so I'll give em a pass ).
