While reading other posts about the nature of music I did some Googling entering such things as "music's effects on the brain" and came across "The Kenny Rogers Effect".

A neuroscientist named David Soto in the UK studied the effects of music on 60 stroke victims and came to the conclusion that listening to music (as opposed to audio books and nothing at all)helped most in their recovery.

He played random music not necessarily the type the patients said they preferred.
However the music that got the best results were The Flying Burrito Brothers, Frank Sinatra and the one one most beneficial, Kenny Rogers.

He said they were thinking of calling the music therapy, "The Kenny Rogers Effect".
His goal was to provide a possible way to help stroke victims without the dangerous side effects of drugs now being used.

I know that Music Therapy is now an accepted course/major in some colleges.

Does that mean to get a degree you have to pass a "bar" exam?
Of chorus!
