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.

The Mute by Radical Face is by far my favorite. If I remember correctly it was written for a relative of the singers, so might not be by someone with autism but it’s a beautiful song.

Helion Prime - Spectrum is one that comes to mind.

I especially like left of center by Suzanne Vega
