"That's not to say they definitely don't do funny things to your brain."

Exactly.

I actually just went in to Ardour and edited down that one "20 Hz" video I mentioned made me feel weird [1] so that it played the loudest part continuously instead of fading in and out, and then listened to it again and after 5 or 10 minutes of listening to it I felt really weird again, and started to get worried about what it might be doing to me, so I stopped.

It's really interesting, though, and I hope some serious research is conducted on this sort of sound's psychological effects.
