“In what year was ‘Rein Me In’ released as a single?” — It was released in 2025.
The collaborative single by Sam Fender and Olivia Dean arrived on 20 June 2025 through Polydor. It was a duet reworking of the original “Rein Me In,” which Fender had already recorded for his third studio album, People Watching.
The collaboration gained momentum after Dean joined Fender onstage at London Stadium on 6 June 2025. They performed the song again at Newcastle’s St James’ Park later that month, and the official studio duet followed soon afterward.
The release date can cause confusion because the song had two closely related versions: Fender’s solo album track and the later Dean duet. The question refers to the single’s release, meaning the duet version issued in June 2025. The song later became a major chart success, reaching number one in both the United Kingdom and Ireland and earning the pair the 2026 BRIT Award for Song of the Year.
