This post is a joy because it is so packed with great listening ideas. I have several in different eras of my life but most have been listed above. When I was a child, six or seven years old, my parents took me to the movie theater to see Kubrick's 2001: A Space Odyssey. I was so enthralled by the images and music even if it didn't exactly have a narrative aimed at kids. That Christmas, in the early '70's, I received my own copy of the MGM soundtrack. I played it on our Sylvania phonograph hundreds of times; I was allowed to use the stereo from a young age. I've loved stereos and music since.
