3 Doors Down lead singer Brad Arnold dies at 47

Brad Arnold, the 47-year-old lead singer and founding member of the rock band 3 Doors Down, has passed away following a battle with stage 4 kidney cancer that had spread to his lungs. Arnold, who wrote the band's breakthrough hit "Kryptonite" as a teenager in math class, helped shape mainstream rock music in the 2000s with emotionally resonant songs that connected with everyday audiences. Beyond his musical achievements, Arnold had been open about his journey to sobriety since 2016 and was deeply involved in charitable work through the band's Better Life Foundation, which supports children in need.
