Query: Used this for years!

We love these beautiful musical arrangements. I bought it because my infant daughter feel asleep in my arms listening to the samples of the music on Amazon. We have now owned this CD for over 4 years and still used it almost every night. We had to buy an extra copy for grandma's house for naps. The only problem is after listening to it every day for 4 years I'm sick of it!
