And the soundlounge award this year goes to…(drum roll please)…a totally brilliant piece of sonic branding from the Coke team of music supervisors. Those who have been following soundlounge’s extensive blog coverage of World Cup advertising music will know that there were dozens of contenders for the crown. However we are all agreement here, that apart from the vuvuzelas, the most recognizable sound from this year’s World Cup has come from a previously little-known Somali-Canadian artist.
Thanks to Coke, K’naan’s song “Wavin’ Flag” has reached an amazing number one in eleven countries (and still counting). With over twenty regional remixes featuring local superstars, “Wavin’ Flag” has become the most popular and memorable soundtrack to South Africa 2010.

Coke has made K’naan an international superstar by modifying his song and promoting the “Coca-Cola Celebration Mix”. But this socially conscious rapper and poet insists this relationship with Coke doesn’t affect his integrity as a musician: “I don’t work for Coke or anything; what I do is my music.” (Billboard).
So isn’t this just a piece of band-brand marketing? Whether or not listeners are consciously aware, Coke have used a technique we call audio watermarking. This is a popular and well-known trick that has been around for centuries and used by composers and producers to weave a sound/motif into a piece of music. Unlike say the Audi sonic logo, which sits at the end of a commercial, watermarking acts like an ‘earworm’, which gets inside our brains and becomes so compulsive that we go around humming it as we walk down the street and not understanding why. We effectively become living, walking, singing commercials for Coke. Whatever K’naan would have his fans believe, embedded into “Wavin’ Flag” is an interesting piece of branding, and Coca-Cola have been priming us to wave their sonic branding flag for a while now…
We’ve actually been hearing this melody for years in Coke commercials. But this time the branding is even less obvious than their original “Open Happiness” song. By sneaking the Coke melody into an otherwise musically unbranded song, they’ve seen incredible success in the charts. In our opinion, it’s a much more intelligent form of branding than paying artists to name-drop brands in their lyrics.
So why doesn’t the average “Wavin’ Flag” fan connect the dots? It took us a few times before the penny dropped and we started to research. It’s as if Coke wants their motif to be subliminal, so that listeners recognize the sound but can’t say exactly why they recognize it. No other hit single has captured the sound of a brand in such an effective and clever way. Even Billboard didn’t come out and say it’s the Coke motif:
‘["Wavin Flag"] features many elements of the original song but includes a pre-chorus that sets the uplifting, unified tone of the 2010 FIFA World Cup, turning the song into one that is “more open, more inviting, more celebratory”‘.
Coke has clearly been steering the ship, taking K’naan on a grand tour of 84 countries. The big question though – what happens after the World Cup? A&M/Octone Records CEO James Diener says that Coke is “invested in K’naan for the duration of his career” (Billboard). That’s a bold statement given the fickle nature of musical popularity. If K’naan loses momentum, will Coke drop him for a fresh new artist or another ‘local’ artist for the next big sports sponsorship? Until then, will they be moderating all of K’naan’s music and infusing it with the sound of Coca-Cola?
You can be sure soundlounge will be listening out for the next Coke advert. And now that you know the Coke motif inside and out, keep your ears open and let us know if you do hear it anywhere else!
