"Wouldn't It Be Nice" is a song by the American rock band the Beach Boys and the opening track from their 1966 album Pet Sounds. Written by Brian Wilson, Tony Asher, and Mike Love, it is distinguished for its sophisticated Wall of Sound-style arrangement and refined vocal performances, and is regarded among the band's finest songs. With its juxtaposition of joyous-sounding music and melancholic lyrics, it is considered a formative work of power pop, and with respect to musical innovation, progressive pop.
