• This song finds Taylor Swift singing of those blissed-out days when you first fall in love. "And I never saw you coming. And I'll never be the same again," she sings.
  
  While previewing the song on Good Morning America, she explained: "I wrote this song about when you first fall in love with someone. The possibilities. Kind of thinking about the different ways that it could go."
• The song marked Swift's first foray into arena rock. Rolling Stone described the tune as a "howling, U2-style epic with reverb-drenched guitars." Said Swift: "It's a really big sound. To me, this sounds like the feeling of falling in love in an epic way."
• An alternative acoustic rendering of this song can be heard on the Deluxe version of Red. "The version on the Target release is really acoustic and like emotional and sweet," Swift told MTV News.
