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.

David Byrne/Talking Heads

I especially like left of center by Suzanne Vega
