unfortunately, i havent seen the advert you're talking about, but i did a search+discovered that there's lots of different versions of the advert, with different tunes playing on each.
in singapore, the song used was 'digital love' by daft punk.
in other countries, the music is 'in all the wrong places' by ulrich schnauss.
confusing or what?!
hope that helps you a bit anyway =]
