From the 14th James Bond film, 1985's A View To A Kill, this is, in my opinion, the greatest Bond theme ever. It's exciting - lots of keyboard riffs to punctuate the excitement. It's time-period appropriate - Duran Duran were at the height of their fame in 1985. Even the video plays out like a spy caper, with scenes from the movie.
It also remains the only Bond theme to reach #1 on the Billboard Hot 100.... and Duran Duran's last #1 (although far from their last hit).
