In 1975 I was living in the Philippines attending a fundamentalist school for missionary kids. Which is to say my exposure to the devil's music was limited. I do vividly recall our music teacher using "science" and all sorts of charts to show us how rock music would warp our souls and lead to demon possession. Still I love your list and while I may not have heard them in '75 many sneaked in soon and still linger in my soul (in a good way).
