Query: If it's not broke - why fix it????

Nothing like the old model. I used the older aquarium for both of my children and they LOVED it. I gave it for every baby shower I went to. This is terrible. All you hear is the motor. The music is not nearly as soothing as the previous model and the back will not stay on. I was terribly disappointed and will never buy one again. I don't know why they had to change something that worked great!
