“Fifteen” is a country pop song performed by American singer-songwriter Taylor Swift. Swift self-penned the song and co-produced it along with Nathan Chapman. “Fifteen” was released on September 1, 2009 by Big Machine Records, as the fourth single from Swift’s second studio album, Fearless (2008). The song was inspired by Swift’s freshman year of high school at Hendersonville High School, where she first encountered heartbreak, along with her best friend Abigail Anderson. After writing it, Swift asked Anderson for authorization to record the song (due to personal references in the song); Anderson affirmed and it was ultimately included on Fearless. “Fifteen” is a ballad, which has Swift reminiscing on events that occurred to her and her best friend at the age of 15 and cautioning young girls to not fall in love easily.
