if it were head banging, we would quickly knock ourselves out and in an unconscious state I suppose we would be relaxed. On the other hand, if it were all soothing, we would soon bewcome bored and fall asleep from lack of interest. But then again, if it were a mix of the two, we would knock ourselves out during the head banging and sleep through the soothing. I guess it will all work ....lol
