Aww, isn't that sweet?
We have Mozart, Bach and Beethoven, but Niall doesn't seem interested. He is the theme tune baby. Regardless of what he's doing, he stops dead every time he hears a theme tune (Corrie, Eastenders, etc), listens to it, then goes back along his merry way. Odd child is our Niall.
He's also starting to recognise children and babies. Each time he sees one in person or on TV, he says, "Eeeeeeeeeeeeeeeeeeeeeeeeeeeeee!" It's so cute.
