omg how many times is this question going to be asked!!! the count must already be at 40, and its on every single section on this site, how on earth it qualifies as Internet and Techology astounds me. But the real killer is that it's not even a good song!. When you asked the question it lists all the questions in which it may have been aswered, just read them yourself. In fact just to spite you i'm not going to give the answer which i happen to know. sorry.
Bad news for you 3styler,that advert is just the first in a series of 3.The next stage is where the girl gets past the security men and makes the basket, and the final one is reckoned to be the Japanese girl singing the song.:-)
