In an interview with America Online (AOL) Taylor Swift was asked if there was a true story behind this song. The teenaged country singer replied: "I wrote this song in my freshman year of high school for my ninth grade talent show. I was sitting there thinking, 'I've gotta write an upbeat song that's gonna relate to everyone.' And at that time, I was dating a guy and we didn't have a song. So I wrote us one, and I played it at the show. Months later, people would come up to me and say, 'I loved that song that you played.' And then they'd start singing lines of it back to me. They'd only heard it once, so I thought, 'There must be something here!'"

In an interview with Blender magazine, Swift said that this song was written about the same guy who inspired "Tim McGraw." One night in 2008 when she was going out, he was in her driveway. She said, "It would have been really poetic and romantic if he showed up right after my album released, but it's been two years. I told him, 'It's really nice to see you. But you're too late.'"

"Our Song" was part of Taylor Swift's self-titled debut album, which went Platinum on June 7, 2007, making the 17-year-old Swift the first female solo artist to write or co-write every song on a Platinum-selling debut album. The album eventually went 7x Platinum.
