It's an ongoing controversy as to whether or not Pink Floyd intended their "Dark Side of The Moon" album to correspond with the "Wizard of Oz" movie. When played simultaneously, some parts of the movie actually relate to the music on the album. Supposedly you must start the album just after the MGM Lion's roar. Personally, I think it's a coincidence. If it really was intended, I think more things would have lined up. What do you guys think?
