Wow, that's so hard to choose. I love so many of them; some of them were crap, but others were simply unforgettable, such as:

Shirley Bassey - Goldfinger (That song set the standard for all Bond Themes)
Carly Simon - Nobody Does It Better
Duran Duran - A View to a Kill
Shirley Bassey - Moonraker (The prettiest of the lot)
Rita Coolidge - All Time High

And so on...

There's so many wonderful themes to choose from!
