It was released on April 18, 2009, by Big Machine Records as the third single from Swift's second studio album, "Fearless" (2008).

"Teardrops on My Guitar" was released on February 19, 2007 by Big Machine Records, as the second single from Swift's eponymous debut album (2006).  The song was later included on the international release of Swift's second studio album, "Fearless" (2008), and released as the second pop single from the album in the United Kingdom.  It was inspired by Swift's experience with Drew Hardwick, a classmate of hers for whom she had feelings.  He was completely unaware and continually spoke about his girlfriend to Swift, something she pretended to be endeared by.  Years afterwards, Hardwick appeared at Swift's house, but Swift rejected him.  Musically, the track is soft and is primarily guided by a gentle acoustic guitar.
