Today Was a Fairytale is a song recorded by American singer-songwriter Taylor Swift. The song was written by Swift and produced by Nathan Chapman with Swift's help. It was released on January 22, 2010 by Big Machine Records as a single from the corresponding soundtrack for the 2010 film Valentine's Day, which she acted in. Swift had previously written the song and offered it to producers for the film's soundtrack. Musically, "Today Was a Fairytale" is pop-influenced and, lyrically, speaks of a magical date.
