A snippet of the song - which was co-written with fun.'s Jack Antonoff - is the second track to be heard from her upcoming fifth studio album, 1989, following the worldwide success of Shake It Off, her first single from the record.
While Shake It Off is about ignoring haters, the blonde beauty explained Out of the Woods is more intimate and based around one of her personal relationships, which has sparked suggestions it is about her romance with Harry, who she became close to at the end of 2012 before their split in January 2013.
She explained: "Out of the Woods is one of my favourite songs on this album because one of the goals I set out to accomplish when I wanted to make this album is I wanted to make these songs sounded exactly the way that the emotions felt when I felt them."
Taylor recently revealed the track is specifically about a serious snowmobile accident with an ex-boyfriend during which he lost control of the mode of transport and crashed it, resulting in them both needing to go to hospital where her then-beau had "20 stitches".
In the tune, she sings: "Remember when you hit the brakes too soon/Twenty stitches in a hospital room."
