"Message in a Bottle" is a song by English rock band The Police. It was released as the lead single from their second studio album, Reggatta de Blanc (1979). Written by the band's lead singer and bassist Sting, the song is ostensibly about a story of a castaway on an island, who sends out a message in a bottle to seek love.
A year later, he has not received any sort of response, and despairs, thinking he is destined to be alone. The next day, he sees "a hundred billion bottles" on the shore, finding out that there are more people like him out there. Over the course of the song, Sting mentions sending an S.O.S. 31 times.
The song was the first of their five UK number one singles. Rolling Stone ranked it number 65 on its list of the "100 Greatest Guitar Songs of All Time".
