O Baby (Robyn song)

"O Baby" is a song by Swedish singer Robyn from her third studio album Don't Stop the Music (2002). Written by Alexander Kronlund and Robyn, it was produced by Johan Ekhé and Ulf Lindström of production duo Ghost, with additional production from Kronlund and Max Martin. The song marked Robyn's first collaboration with Martin since 1997's "Show Me Love". A pop ballad backed by organ, piano, and string arrangements, "O Baby" was issued as a promotional CD single by BMG Sweden and distributed to Swedish radio stations in 2003.

Music critics were ambivalent toward "O Baby", with some feeling it was aimed at commercial appeal and lacked substance. Following its promotional release, the song garnered significant airplay and attained top-ten positions on both the Svensktoppen and Trackslistan radio charts. It ultimately ranked as the fifth-most-played song on Swedish radio in 2003. Robyn has performed "O Baby" live on numerous occasions, including Allsång på Skansen and the 2003 birthday celebration of Victoria, Crown Princess of Sweden.
