It was the first "real" James Bond song (again, the first two films only opened with orchestral music), and it's still the best. Shirley Bassey got an opportunity to sing her soul out and she accepted the challenge with obvious pleasure. This is a song that makes the villain Auric Goldfinger seem a lot more threatening (and attractive) than he actually is, but that's part of the miracle of Bassey's work here. It's proud and heroic and enticing and it's kind of a lie, but who cares? The music is pure James Bond, the lyrics are pure machismo, and the performance is perfect.
