Taylor Swift announces that her new single entitled "White Horse" will be launched on Thursday night, September 25 during the premiere of "Grey's Anatomy" season five. "Finding out I have a song in 'Grey's Anatomy' was one of the very few times in my life I've broken down crying out of happiness," Taylor says.

Speaking of the big night, the country singer shares her excitement, saying that her dream to perform on the show has finally come true. "That show is my biggest obsession and my longest relationship to date. Ha! I'm so happy, I don't even know what to do with myself," she adds.

"White Horse" is a song where Taylor narrates about someone that she dreams on but has never become hers. "It talks about falling in love and the fairy tales that you are going to have with this person," the singer states. "Then there is that moment where you realize that it is not going to happen. That moment is the most earth shattering moment."

Another single, that will appear in Taylor's sophomore studio effort, "Fearless", is called "Love Story". The song has been released earlier this month and peaked at number 18 in Billboard Country Hot Singles chart and reached at number 8 in Billboard Digital Hot Songs chart. However, fans will not get access to purchase her second album until November 11.
