Taylor Swift reveals she's releasing new music: 'You'll hear it soon'

Taylor Swift announced today that she is releasing a new song called Carolina.

The 32-year-old singer-songwriter wrote the track "alone" and produced it alongside long-time friend and music collaborator Aaron Dessner, 45. The pair co-produced Taylor's critically acclaimed eighth and ninth studio albums, Folklore and Evermore.

The song is set to feature in the upcoming movie version of Where the Crawdads Sing - based on the 2018 murder mystery novel by American author Delia Owens - and a clip of the song can be heard in a new trailer for the movie, released yesterday. The movie will star 23-year-old Normal People actress Daisy Edgar-Jones, and will be produced by 46-year-old actress Reese Witherspoon.

The Cardigan singer wrote in an Instagram caption: "I wrote the song 'Carolina' alone and asked my friend @aarondessner to produce it. I wanted to create something haunting and ethereal to match this mesmerising story."

Carolina does not have an official release date yet, but Taylor added that the full version will be available "soon".
