4. 'Skyfall' (Adele)
The most popular Bond theme of all time (if you go by YouTube play counts), "Skyfall" was money in the bank from the moment Sony decided to hire Adele. Channeling that vintage Bassey sound and flexing it with serious symphonic muscle, this epic tune played no small role in helping make this blockbuster the the first Bond movie to gross more than a billion dollars. As with the other songs written for the Craig-era installments, "Skyfall" eschews the franchise's classic innuendo in favor of bleating emotional abstractions, though some of the words here ("Skyfall is where we start…") tease at crucial third act plot details. In fact, the lyrical nonsense works to the song's advantage, leaving Adele's booming voice free to launch the tidal wave of sonic pathos that will carry this consequential Bond movie all the way to its grim conclusion.
