Picture Bools with Music!

There are some picture books are sold with music CDs. Some of them are just music that you can hear while you are reading. Some of them have a signal that tells you when you should flip the pages, so that the music tone/ spread will goes with the story and create a certain mood that fit the page. It is especially useful to describe the feelings you have when you are reading, for example, fear when the monster comes out, or happy when it's got a good ending.
