Title: Purposly screwed up!! Review: Synthesized junk from start to finish. Most of the time the music doesn't match what you see being played, and the sounds are laughable. Even when the music matches what the musicians are playing (like the piano section) they over-dub a synthesized version... like kids prefer electric sounds to real instruments! Truly awful. I'm really mad. They had such an opportunity to be educational and PURPOSLY SCREWED IT UP!!! Save your money and go hear a REAL orchestra.
