Image Credit: Kevin Mazur/“Back to December,” another new song from Taylor Swift’s upcoming album Speak Now, has hit iTunes, and it’s making headlines because, for the first time, she’s the one who needs to apologize for her behavior in a relationship. Swift, known for her autobiographical songwriting, has already admitted it’s “almost word-for-word” a conversation that she had with a young man whose heart she broke. She wouldn’t name him, but fans are assuming it’s Twilight‘s Taylor Lautner. In the tune — a melancholy mea culpa with the kind of driving chorus and age-appropriate yet universal honesty that makes Swift’s songs hits — she says she’s sorry for the last time he saw her (“You gave me roses, and I left them there to die”) and that she wishes she realized what she had (“I’d go back to December, turn around, and change my own mind/I go back to December all the time”). At the risk of going Teen Beat on you, here’s why the Lautner guess isn’t a bad one:

– “Then I think about summer all the beautiful times/ I watched you laughing from the passenger side/ And realized I loved you in the fall/” — They filmed Valentine’s Day in summer 2009. She was photographed, smiling, in his passenger seat last October. And she sung about him in her Saturday Night Live opening monologue in November.

– “When your birthday passed, and I didn’t call” — Lautner turned 18 in February.

If you’ve heard the track, does it sound like a hit? I’m sorry for the boy’s heartbreak (“You gave me all your love, and all I gave you was goodbye”), but grateful that Swift has a new side of love to write about — regret.
