Actually I remember reading a really good book written by a professor here in OZ who studied rhythm and reiterative music and its effects on us. Very serious stuff. I will have to see if I can find it and read over it again. There were some experiments done by Russian scientists to measure the effects of reiterative music on a person. They said that it even effected our DNA someway....cant remember exactly how??

I'll get back to you on this one.
