Some of y'all don't know what a "musical" is.
In a musical, the characters themselves sing (and typically dance), with the song as central to the story, revealing the character's nature, desires, and even values, and advancing either theme or plot.
A great soundtrack of classic popular hits is NOT a musical.
One character singing one song, however iconic, is NOT a musical.
Instrumental theme music, even if central and inspirational to the film is NOT a musical.
American Graffiti, however much you may like it, is NOT a musical.
Fantasia, as fun as it is to see dancing hippos, or Mickey battle a bunch of animated mops, is NOT a musical.
I realize this is a website for people somewhat out of the mainstream, but jeez.
