38. Morgan Wallen

Morgan Wallen went from reality TV contestant to country music’s fastest-rising star, with back-to-back chart-topping albums and sold-out arenas by 2020–2021. Nashville and streaming giants had him pegged as the next decade-defining country superstar.
In February 2021, video surfaced of Wallen using a racial slur outside his home. Radio stations blacklisted him, awards shows dropped him, and his label suspended promotion. Though he later rebounded somewhat, the scandal permanently altered his path to undisputed mainstream dominance, costing him millions in momentum and partnerships.
