I love Chopin. I wish I could play the piano. (Of course, the fact that I can't read music might make that a little difficult...;-D)

I've loved Gene Kelly and Fred Astaire all my life. The first movies I ever saw were all musicals. Definitely check out "An American in Paris", "Singin' in the Rain", and "Easter Parade" if you haven't seen those yet. (And "Easter Parade" has the added bonus of Judy Garland; ANYTHING with Judy Garland in it is worth seeing!)
