"Lover" is a song by American singer-songwriter Taylor Swift for her seventh studio album of the same name (2019). Swift wrote the song and co-produced it with Jack Antonoff. Republic Records in partnership with Taylor Swift Productions released it as the third single from the album on August 16, 2019. Musically, "Lover" is a country ballad that features a booming snare, slow tempo and guitar-centric sound. Over a retro-styled musical motif, Swift sings lyrics about devotion on the song; which several publications interpreted to be about her partner.
