Message in a Bottle (Taylor Swift song)

"Message in a Bottle" is a song by the American singer-songwriter Taylor Swift. It was her first writing collaboration with Max Martin and Shellback. The song was intended for but excluded from her fourth studio album, Red (2012). Shellback and Elvira Anderfjärd produced the track for Swift's re-recorded album, Red (Taylor's Version) (2021). "Message in a Bottle" is a 1980s-influenced dance-pop, synth-pop, and electropop song with lyrics about the anxiety from falling in love.

Republic Records issued the song to the US hot AC and mainstream radio formats as a single following the album's release in November 2021. Music critics generally praised the song's production as catchy, although a few found it underwhelming. The song peaked at number 50 on the Billboard Global 200 and charted in Australia, the Canadian Hot 100, and the US Billboard Hot 100, among other countries. It also peaked in the top 20 on three Billboard airplay charts.
