Jack White, one half of the Whites in the White Stripes, wrote and produced the new theme song for Quantum of Solace, sung by White and Alicia Keyes. Turns out that White also -- unwittingly and unhappily -- wrote the new theme song for Coke Zero. Coca-Cola has used an instrumental version of "Another Way to Die," as well as a couple of Astons, to promote its diet drink that tastes like a diet drink even though they say it doesn't. In our opinion, the commercial gets a resounding "meh," but the song is thoroughly groovy. Follow the jump to check it out. Thanks for the tip, Marcus!
