Taylor Swift has shared four previously unreleased songs. The superstar shared the news via an Instagram story yesterday (March 16), writing: "In celebration of The Eras Tour I'm releasing 4 previously unreleased songs tonight at midnight."

The four tracks include re-recordings of Swift's dual contributions to the 2012 soundtrack to The Hunger Games — "Eyes Open" and "Safe & Sound" featuring Joy Williams and John Paul White — as well as "If This Was a Movie (Taylor's Version)" and a never-before-heard track "All of the Girls You Loved Before."

Swift opens the U.S. leg of her tour tonight on Friday (March 17) at State Farm Stadium, the same location where the Super Bowl was held last month. She plays the same venue the following night (March 18).

As Swift opens 'The Eras Tour', it will be celebrated with a temporary name change in Glendale.

A host of special guests including Paramore, beabadoobee, Phoebe Bridgers, girl in red, MUNA, Haim, Gayle, Gracie Abrams and Owenn are set to join the singer-songwriter on the tour, which is in support of her latest chart-topping album Midnights. Swift is expected to put on a career-spanning show.

Since the Reputation tour wrapped in 2018, Swift has released four original studio albums - Lover, 2020's Folklore and Evermore, and Midnights - as well as two re-recorded albums, Fearless (Taylor's Version) and Red (Taylor's Version) in 2021.
