No help for your question, just a little more speculation. If there is some correlation, I wonder if it would be measurable less while dancing than with idle music listening. I can see where there may be some sort of measurable response to beat while the body is at rest, but while dancing, it seems as though the circulatory system's primary function would trump any external stimuli, at least as far as the effect being measurable.
