I bought this Little house book through used bookseller since it is unavailable new. I specifically bought the one that had a comment saying that the song still played. It played beautifully. Twice for me when it first arrived, and twice for Rose which made her day - then it quickly began distorting and now is nearly inaudible. This ranked as her favorite gift, and it's very frustrating. It is the metal button set in the book variety and doesn't seem to be made to be changed, but has anyone ever tried to change it anyway? Thanks.
