Swift re-recording old songs, releasing some "From The Vault"

Swift has started to re-record her old albums so that she can have ownership of them, beginning with 2008's Fearless. Recently, she debuted her new version of "Love Story," giving the Romeo and Juliet-themed hit an update and adding the label "(Taylor's Version)" to it. She also shared a message on social media revealing that Fearless (Taylor's Version) will be released on April 9!

And while Swift's latest track "You All Over Me" may be new to fans, it's actually one of the songs that was cut from Fearless! The singer first tweeted about the song on Wednesday, sharing that it was one of the 6 upcoming tracks featured on the album that comes "From The Vault" of her previously unreleased material.

Swift says she's "really excited" to collaborate with Morris

Swift explained that since her "From The Vault" songs have "never been heard" until now, she's had the freedom to "experiment, play, and even include some of my favorite artists"— including Morris! "I'm really excited to have @MarenMorris singing background vocals on this song!!" she wrote.

She also expressed her excitement for fans to hear "You All Over Me," sharing that the track is co-written by Scooter Carusoe and produced by Aaron Dessner. Earlier this month, Swift took home Album of the Year at the Grammy Awards for folklore, while Morris was nominated in the Best Country Song category for her hit, "The Bones"!
