Ed Sheeran

Ed Sheeran's 150 million records sold mark him as a commercial giant, but his acoustic pop formula has become stale, with his last album scoring just 52 on Metacritic—10 points below the industry average for top-charting artists. This overreliance on sentimental ballads leaves him trailing more dynamic acts, failing to match the experimentation of #5 Coldplay even in their weakest moments, as evidenced by Coldplay's 67 average across later releases.
