Sam Fender and Olivia Dean's 'Rein Me In' Is Now the Longest-Running No. 1 Single of the Decade

Sam Fender and Olivia Dean's collaboration "Rein Me In" is now the longest-running No. 1 single of the 2020s in the United Kingdom, according to a report from Billboard.

The track has earned 16 weeks at No. 1 on the Official Singles Chart. This milestone means it has surpassed Alex Warren's "Ordinary," which notched 13 weeks last year. 1 in the 21st century.

How Did the Song Get Its Start?

The song's journey began as a live debut. Fender first performed it with Dean during his headline show at London Stadium in June 2025. A studio version of their collaboration was released two weeks later. Richard O'Donovan, head of A&R at Polydor, told Billboard U.K. that "having these two extraordinary UK artists together on a track created so much fan excitement." He noted the live footage from that stadium show "exploded online and took the song to a new level."

What Other Success Has It Seen?

Beyond its chart dominance, "Rein Me In" has collected major awards. In February, it earned the BRIT Awards' publicly-voted Song of the Year prize, which Fender and Dean accepted in Manchester. The track also gave Fender his first career No. 1 single. It currently sits at No. 83 on the Billboard Hot 100 chart in the United States, as of July 2026.

The song's sustained popularity underscores a remarkable turnaround for British pop music on the global stage, built from a single stadium performance.
