Music Please

This is Vera's all-time favourite toy. When we make her press the buttons, they light up, and so does her face as well (or at least she'll stop fussing). In fact, her clenched fist will sometimes open up even, in preparation for pressing the buttons. She's definitely getting the hang of it.
We know it's not just the lights, but more the nursery rhyme music. Other musical toys seem to work as well. So, can Vera hear some? We don't need a test to tell us that.
