Music and movies evolved at the same rate from the early 20th century onward. They improved substantially in quality and complexity.
Sound is organized and has a purpose whereas noise is random. Sound is inserted in a logical way to help tell a story.
Sound can be seen as color, with encoded sound at one end of the spectrum and embodied sound in the other. Language is encoded and music is embodied, most sounds fall somewhere in between and all have their own colors.
