TAYLOR Swift says writing about her private life makes her "very vulnerable".
The 'I Knew You Were Trouble' hitmaker has begun recording songs for films and sees it as a different kind of "thrill" compared to the "intense" process of baring her own life on record.
She told Billboard magazine: "I think it's a bit of a relief to take the focus off of my own life.
"It can get pretty intense writing [personal] details - that's a very vulnerable place to put yourself in.
"But there's a specific type of thrill you get from that recounting of your life."
The 24-year-old singer recorded the song 'Sweeter Than Fiction' for 'One Chance' - the movie based on the life of 'Britain's Got Talent' winner Paul Potts - and was proud of getting "someone else's emotions" across in the right way.
She added: "There's a different kind of thrill you get hoping you have accurately portrayed someone else's emotions that you're seeing so well done by these actors, James Corden and Mackenzie Crook.
"The actors did such a great job it was fairly easy to get inside their heads."
