I actually wonder if staying receptive to new music into or past middle age is enhanced by autism. I am a male on the spectrum, in my late 30's, and absolutely nothing about this article rings true to me. I generally operate on a 5 year cycle where I completely reinvent my musical interests, stop enjoying lots of tracks that I used to love (I hate just about eveything I loved at 14), and hang onto a handful of tracks that I consider timeless.
I am already feeling myself reach the end of one of these cycles where I am digging through netlabels and indie internet radio stations looking for the next niche subgenre to become addicted to.
