Last year, Mr. King was referred to Dr. Victor Aziz, a psychiatrist at St. Cadoc's Hospital in Wales. Dr. Aziz explained to him that there was a name for his experience: musical hallucinations.
This is interesting. I've had an ongoing interest in some of the finer points of the way we perceive music and relate it to memory.. I'm pretty sure I meme'd an article awhile back, which I can't seem to find, that went into some detail about how our brains and by extension our bodies react to musical patterns. The short of it was that some people are more likely then others to have their psychology follow music patterns they are exposed to. For instance, if you are listening to music that has a beat that's somewhat close to your heart-beat, your heart-beat will adjust to match the beat of the music. You are also more likely to preform physical actions like arm movements or walking in beat. This is the case with everyone, but its more prevalent with some people. Apparently some people are so susceptible to it that its hard or downright impossible to do things out of beat when exposed to one. One of my favorite oddities, which you can catch yourself do: When you pause or stop music, you are more likely to do it directly in the middle off the song then at any other point. The reason for this is that it "feels right", and you do it unconsciously. Most musical compositions that "feel complete" have the tendency to rise and fall, and display elements of symmetry across their composition. Classical music and pop songs in particular..
