Diamonds Are Forever was the seventh James Bond film, released in 1971, and its title theme, performed by Shirley Bassey, became one of the series' most recognisable musical signatures. The lush, dramatic style helped define the sound of classic Bond glamour, and short clips of the theme now circulate widely as soundboard and video-editing sounds. Creators keep using it because the opening instantly signals wealth, elegance and spy-movie confidence without needing any explanation.
