I love that McDonald's commercial with the kids who win the soccer match but want to know the song?

Question

Anyone know the song? The commercial shows the soccer kids winning and bragging with their body language. The kids who lose look so sad, until they get Happy Meals.

I want to know if anyone knows the song?
