Someone told me when I was a kid, that if our eyes did not close when we sneezed, our eyeballs would go flying out of ther sockets.....
I think I can answer that - because we think in auditory terms, literally "talking to ourselves." Even though we may not actually speak aloud, we associate thoughts with spoken words, and form words to express our thoughts, and "listen" to the subvocalized thoughts with our ears. Music interferes with that subvocalization and listening process which we would use while searching for something.
