There's only been one guaranteed success in the World Cup so far, and that's Somalia. If holding the competition in South Africa was supposed to raise the profile of the continent as a whole, then it's only right that the world's most popular football anthem of the moment should be sung by an exile from what K'naan accurately describes as "the hardest place on earth right now". Unsurprisingly, his gloriously uplifting Wavin' Flag appears three times on an album that's been repackaged to coincide with the song's success (it's currently near the top of the British singles chart). There's the bestselling Coca Cola Celebration Mix, with lyrics about "the beautiful game", another remix featuring will.i.am and producer/DJ David Guetta, and (best of all) the original version, a more low-key, thoughtful song of struggle, perseverance and escape that appeared on the original Troubadour album last year. Other songs from that set show K'naan's skill in mixing hip-hop and more mainstream pop with finely observed lyrics about the horrors of his homeland, love or the music business. Those who have not heard him should check out Somalia, which matches a cheerful girl chorus against lines such as "she got a gun but she could have been a model or physician"; or Fatima, a pained and personal song of love, loss and death. K'naan is that rarity: a true original.
