While not exactly considered to be a musical instrument, a music box is still a well loved toy that collectors all around the world are after. This music box has been equipped with buttons that you can press to make the box generate a different song. Unlike musical boxes in real life that already have songs prerecorded, this digital music box lets you play any song you want. All you need to do is to push the buttons like tapping keys on a piano to create your own brand of music.
