5. Shirley Bassey, 'Diamonds Are Forever' (1971)
To American audiences, Shirley Bassey is known almost entirely for her James Bond title songs. 1971's Diamonds Are Forever was Sean Connery's final Bond flick (at least until the non-canon entry Never Say Never Again), and for the occasion they brought Bassey back to belt out the title song, just as she had done for 1964's Goldfinger. They brought Bassey back one more time in 1979 to sing the Moonraker theme, but she couldn't quite recapture the magic. Decades later, "Diamonds Are Forever" returned to pop culture when Kanye West sampled the song for "Diamonds From Sierra Leone."
