Here it is, the 22nd James Bond theme; "Another Way To Die" by both Jack White and Alicia Keys will be the opening theme to Quantum of Solace. This is the first duet for a James Bond theme, and as can recall, it is the 3rd film not to be named after the film or contain its name in the lyrics. Basically it's following Casino Royale by having American artists, as well as not mentioning the film.
Personally, I think the Chris Cornell track, "You Know My Name", was a much better song than "Another Way To Die". This new track sounds like a Bond song at first, which is promising, but then it just sort of drops. Originally, Amy Whinehouse was selected to do the film's theme, but then she went to rehab, and that's the end of that story. I would have liked that they picked an English band or musician to do the theme, because lately they seem to lack any British influence; Whinehouse was a step in right direction, but maybe someone more stable next time?
You can check out the song for yourself, here, if you don't feel like being surprised when the movie releases this November.
