Taylor Swift, Darius Rucker Split the Country Singles Charts

Taylor Swift's 'Mine' has climbed to the top of the Mediabase/Country Aircheck chart, while Darius Rucker's 'Come Back Song' spends a second week at No. 1 on the Billboard country singles chart. The two switch places at No. 2 on both charts, followed by Sugarland's 'Stuck Like Glue' at No. 3.

"It's a song about my tendency to run from love," Taylor revealed about 'Mine' during her online chat this past summer. "It's sort of a recent tendency. I think it's because, for me, every really direct example of love that I've had in front of me has ended in goodbye and ended in breakups and things like that. I think I've developed this pattern of running away when it comes time to fall in love and to stay in a relationship. This song is sort of about finding the exception to that and to finding someone who would make you believe in love and realize that it could work out."

Taylor is currently in the midst of a promotional blitz surrounding the release of her album, 'Speak Now.' Today (November 1), the superstar will appear on the 'Ellen DeGeneres Show,' where she artfully dodges questions about her love life. That precedes a performance on ABC's 'Dancing With the Stars' on Tuesday, November 2.

Later this week, we'll find out just how many copies of 'Speak Now' were sold in the album's first week of release in the next. Industry estimates range anywhere from 500,000 to one million.
