Taylor Swift Makes History … Again

Country sensation Taylor Swift has made the musical history books again. With the 17-year-old's current hit, 'Our Song,' on the top of the charts this week, she's the youngest artist ever to single-handedly write a No. 1 country hit entirely on her own.

"I wrote this song in my freshman year of high school for my ninth grade talent show," Swift tells AOL Music in an exclusive interview. "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!'"

This is the second time Swift has made history in 2007. When her debut album hit the million mark in sales, she became the first female solo artist in country music history to write or co-write every song on a platinum-selling debut CD.

In fact, when Taylor joked, "This is the definitely the highlight of my Senior year," after winning the CMA's coveted Horizon Award, she didn't know what the rest of the year would have in store for her. Last week, she received the news about her album reaching double platinum status just hours before receiving a Grammy nomination for Best New Artist.
