I know this was brought up in another area. I received my PE Hot Chocolate Car and was prepared for the lack of the song "which was promised". It was an insult to injury when I peeled a sticker off the end of the box. These apparently made it all the way to packaging with the intent to supply as described.
I wish we would have been informed before shipping. At least it would have softened the shock. I can only guess there may not have been enough memory to put the song on. Maybe someone can get a real answer in April at York.
