Bond film themes are one of my guilty pleasures.
My favorite to this day is still Tom Jones' "Thunderball". Just a classic big band bombastic Bond theme. I still get goosebumps when he hits that last note:
An underrated theme from my teenage years was Sheryl Crow's theme for Tomorrow Never Dies:
Adele's Skyfall is the only Bond theme I can think of that I ever heard on the radio (why I heard it at a Taco Bell of all places, I will never know)
Of course, I can't go without mentioning the first Bond film I ever watched: The Living Daylights
