Musical Obsession of the Week

Last weekend, I caught a few minutes here and there of an old movie (The Black Cat). I didn't see enough of the movie to say anything about the plot, but whoever was in charge of the music did a good job of choosing memorable bits of classical music.

I recognized the melody of this one, but couldn't remember the name or composer.  A little investigating online-- and here it is!  ...And now it keeps coming back to me.  (There are worse things to have stuck in your head. (g))

The best part (imho) is the first two and a half minutes.
