What is the name of the songs on the sims 2 for PC that you can play on the piano?

There are no names for the songs you play on the piano for Sims 2 PC. There are 3 different genres of music you can choose from for the piano: Classical, Rock, and Jazz. Some of the music, though, are actual pieces of music. It just doesn't tell what the names of them are. There is more than likely a mod out there somewhere where you can change that.
