Car Advert Theme Tune

[[kiss][kiss]]

There is a car advert, with a young girl running in and out of her room, with assorted objects. One minute she is being a fairy, the next a footballer, and so on. The catchphrase for the car is 'ready for the next big thing' and I would really like to know what the song is! There is a song in the background and I love it and I don't know what it is! It's driving me mad!
