“Mine” is the lead single from Taylor’s third studio album Speak Now.

It tells the story of a girl whose parents' failed marriage has caused her to take a pessimistic view on love. Over time she falls in love with someone who convinces her to start believing in love again, but she still fears that something will go wrong.

This song is rumored to be about the late Glee actor, Cory Monteith. The pair hung out briefly between January and April 2010, and were pictured bowling with Selena Gomez.

The hidden message for the track is “Toby” which is in reference to her music video co-star, Toby Hemingway. The pair never had a romantic relationship, with Taylor stating that she picked him after spotting him wear her lucky number 13 on a t-shirt in his movie, The Covenant.
