Well that explains a lot. I had no idea that this was a thing, although I seem to recall an MP3 I had on my phone which was a "3D" recording of a barber-shop. The whole thing gave me a weird sensation in my scalp as I listened to it. After that I realised that a lot of sounds do that. At the moment I'm really into Dubstep/Techno/Electronic music - when I hear a song that is really well layered (think Skrillex, Madeon) and you hear one of the lower layers like a tambourine or a tiny synth it will give me the same feeling. I can't explain why, but it's something about it.
