I could try. According to the Trivia sections of episode articles of this Wiki, the following have Chopin's works: I hope this helps!
 * The Choices has "Raindrop Prelude"
 * The Understanding has "Funeral March"
 * The Blame also has an 8-bit version of the Funeral March
 * The Fuss uses Funeral March as well
 * The Loophole uses it as well (geez, that's a lot of episodes with the same piece!)
