Not only is it one of her most beloved hits, but it also means that the first new-old lyric we hear the 31-year-old Swift sing is, “We were both young when I first saw you” - an immediate invocation of the past that subtly reframes the recording as a kind of tender love song to her 18-year-old self. As the first official release of her rerecorded back catalog, “Love Story,” from Taylor Swift’s 2008 album, “Fearless,” is a savvy pick.
