A new song by Taylor Swift will debut on the two-hour season premiere of ABC's Grey's Anatomy on Thursday (Sept. 25). The song will also be included on Swift's upcoming album, Fearless, which will be released on Nov. 11. "It's one of the songs that I am really proud of on the record because it's so sparse -- it's guitar, piano and cello," Swift told Billboard magazine. "It talks about falling in love and the fairy tales that you are going to have with this person, and then there is that moment where you realize that it is not going to happen. That moment is the most earth-shattering moment."
