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. This overreliance on sentimental ballads leaves him trailing more dynamic acts, failing to match the experimentation of Coldplay even in their weakest moments, as evidenced by Coldplay's 67 average across later releases.
