Sam Fender and Olivia Dean's collaboration has achieved an historic milestone in British music history. Their single 'Rein Me In' has spent 22 non-consecutive weeks atop the UK Official Singles Chart, surpassing the previous record of 18 weeks set by Frankie Lane with 'I Believe' in 1953. The track had already claimed several major distinctions before reaching the all-time top: it became the longest-running number one by a British artist and the dominant single of the 21st century on UK charts.

The song's success has extended beyond traditional radio and streaming into the social media sphere, where it has maintained significant traction on TikTok in North America over recent months. Following the artists' performance at Lollapalooza, the track climbed to number 50 on the Billboard Hot 100. Capitol Music Group executives have indicated the song is part of a broader strategy to build the artists' audience internationally at a measured pace, suggesting the collaboration's chart dominance may continue expanding into new markets.
