This reworking of Rein Me In, from Fender's third studio album, the Mercury Prize-winning People Watching, features an extra verse about the breakdown of a relationship from a female perspective, from Dean. "[It's] very personal and reminded us of home, but when Olivia put her touch on it, it became a much more universal track," he told Radio 1, adding "that's what made it so huge and so beautiful". When asked how he'd be celebrating the achievement, Fender joked "I think I'm just gonna have a really big sandwich". Dean said when the track came out, external that the original version of Rein Me In was her "favourite song on Sam's album" and it was "a pleasure to write a new verse from a female perspective". It has been described by Blunt Magazine's Jake Fitzpatrick, external as "stormy, tender and anthemic" and a "love letter to the kind of songwriting that knows when to burn slow".
