“Rein Me In” reached number 37 on Belgium’s Ultratop 50 Flanders chart.
The chart listing refers to the Flemish-region edition of Ultratop, Belgium’s official music-chart system. It is separate from the Ultratop chart for Wallonia, so the regional label matters when reading the table. The song is credited to British singer-songwriters Sam Fender and Olivia Dean and was released as a duet in June 2025.
The track began as a song on Fender’s album People Watching, where the original version featured Fender alone. Dean joined him for the re-recorded duet, which became the commercially charted collaboration. A common mix-up is to confuse its Flanders position with another country’s airplay ranking or with the song’s UK peak of number one.
The Flanders result is a weekly-chart peak, not a year-end position. That distinction matters because “Rein Me In” also appears separately in the table’s 2025 UK year-end chart, where it ranked number 38.
