I have a music box that uses a paper tape, it was an extra as I was making a gift for a family member and Thinkgeek (long before the Gamestop acquisition) accidentally sent me two. It was actually a lot of fun to make extra songs for it, the toy becomes interactive for the player. Which is a much better thing for kids than something that can only ever play 10 songs, and which they cannot alter in any meaningful sense.
