[Zancarius]

It seems plausible. I'm not on the spectrum (so far as I know), but my receptiveness to new music generally has some association with previous genres I enjoyed. I definitely don't experience the "reinventiveness" trait so much as gradual evolution. I don't like early 2000s electronica anymore, some trance I used to enjoy I don't, but now I just love some other genres that are tangentially related (chillstep, etc). On the other hand, I still enjoy some of the same metal groups that I used to (Disturbed, Epica, etc) even though I don't listen as often.

Perhaps there is, if you pardon the expression, a spectrum of receptiveness.

I'm thinking there's something to your speculation, though.
