Taylor Swift's new single "Mine" has officially been released to radio and iTunes after the song leaked online Wednesday (Aug. 4). Originally slated for an Aug. 16 premiere, "Mine" is now poised for a big debut on the Billboard Hot 100 chart next week.

"I was a flight risk with a fear of fallin'/Wonderin' why we bother with love if it never lasts," a jaded Swift sings on the opening verse of the guitar-driven country track and lead single from her upcoming album, "Speak Now." On the chorus, Swift recalls the moment she fell for the object of her affection. "Do you remember we were sittin' there, by the water?/You put your arm around me for the first time/You made a rebel of a careless man's careful daughter/You are the best thing that's ever been mine."

Swift's happy relationship takes a turn for the worse on the bridge: "I remember that fight, 2:30am/You said everything was slippin' right out of our hands/I ran out cryin' and you followed me out into the street." In the end, Swift's nameless love interest doesn't let her go. "Brace myself for the goodbye, 'cause it's all I've ever known/Then you took me by surprise, you said I'll never leave you alone." 

Will Taylor Swift's New Album Sell a Million in Its First Week?

Swift talked about "Mine" at length while announcing the release of "Speak Now" in July, explaining that the song is about "my tendency to run from love...Every really direct example of love that I've had in front of me has ended in goodbye and has ended in breakups and things like that. So I think I've developed this pattern of sort of running away when it comes time to fall in love. This song is sort of about finding the exception to that." 

Swift will perform "Mine" Sept. 1 on the ABC special "CMA Music Festival: Country's Night to Rock."
