Big and brassy! Paul McCartney (yes, yes, and also Wings) ushered in a new era of James Bond movies with the theme to Live and Let Die, sending the series careening into a 1970s musical sound as the franchise rebranded itself with a new leading man, Roger Moore. This is an almost maniacally excited song. The melody shifts and spirals and builds and sinks and hardly gives the listener a chance to get their bearings. It's a thrill.
