As the best-selling musical act in history, The Beatles reign supreme with over 600 million records sold worldwide. Despite their primary creative peak lasting only eight years, their cultural endurance is staggering—demonstrated by the 2023 release of their 'final' song, Now and Then, which immediately topped the charts. In terms of sheer scale, they outperform even the most iconic solo superstars like Michael Jackson or Elvis Presley, setting a benchmark in global music industry penetration and cultural influence that remains virtually unrivaled.
