10. 'Moonraker' (Shirley Bassey)
There are no two ways about it: Shirley Bassey is the voice of the Bond themes, and even her weakest contribution ranks among the series' most essential tracks. Stepping in for a frustrated Johnny Mathis mere weeks before the film was due for release, the chanteuse reminded the world that she was one of the only Earthlings who could croon a nonsense word like "Moonraker" and make it sound downright glorious. Listen, you try taking a mess of typically distressed Bond lyrics ("Where are you? When will we meet? Take my unfinished life and make it complete") and imbuing them with sense of life or death. Not so easy, is it?
