Coca Cola were one of the very first companies to see the link between making a song familiar as an ad., then releasing it as a hit song, which makes a hit record, which subliminally reinforces the original ad, and therefore their product. They've been doing it since the late 1960's with 'I'D Like To Teach The World To Sing' and there's no reason to assume they won't do the same here. Give it a few months, and this song will be a radio hit worldwide. Cynical? Moi?
I just managed to download the nina simone song, its very different to the advert, much more up-tempo - good song though, hopefully the version from the advert will be released also. The Lighthouse family released a cover of it too, don't rate it though!
