Helion Prime - Spectrum is one that comes to mind.

I have a playlist actually, I’ll reply to my own comment here with the Spotify link tomorrow

I don’t know about songs that sing about autism but I know of a couple of binaural songs that tickle my brain and they’re by Rob Zombie. They’re all from the Lunar Injection Kool Aid Eclipse Conspiracy album. The first one that comes to mind is The Ballad of Sleazy Rider.

I’m a middle aged autistic guy and David Bowie always hits the right spots for me. He’s got such an outsider- looking-in perspective to his music that I really think he was a super highly functional autistic who just didn’t give a damn about masking.
