I’m quite partial to John Barry’s score for The Living Daylights. I just adore the themes used throughout and the heavy use of sequencers. Barry truly left Bond on a high note (pun intended). I’d put the score for OHMSS just behind it. Both are among his best work in the series.
I also love David Arnold’s work with the series. He may have leaned a little too heavy on the electronics for Die Another Day, but overall I find his scores very listenable with Tomorrow Never Dies and Casino Royale being my favorites. He’s no John Barry, but that’s not a bad thing. He’s David Arnold, and I like him a lot.
