Think of it as a response to The Ronettes' “Be My Baby.” The hot-rod hit “Don't Worry Baby” is the cheery B-side to “I Get Around," and has one of the most transformative key shifts in pop music history, from the man's perspective in the verse to the woman's response in the chorus. Brilliant!

"Caroline, No" was released as the first solo Brian Wilson song in 1966, and then appeared as the closing track on the legendary Beach Boys album Pet Sounds. The melancholy lyrics and creative instrumentation—including harpsichord, vibraphone, a tambourine hit with a wood block and a water jug hit with a mallet—is classic Wilson.
