What's the name of this song? in a commercial? ?

Here's what I could pick up,

"It's like the fast music, playing in the air.."

(and I'm not sure if it's air or ear and vast or fast)

"but the music is impossible, impossible to hear.."

"and suddenly I'm flying, flying like a bird.."

It's in like a circus commercial well not a circus commercial more like a acrobats commercial you could find this commercial on the dvd for Mamma Mia and I think a Chinese woman is singing it. Help??
