3. "Fade to Black"
Metallica fans have been accusing the group of selling out all the way back to the release of this 1984 song, which was the group's first ballad. It's a dark track about depression and suicide, and in a bizarre twist of fate James Hetfield nearly died while performing it in 1992 on a co-headlining tour with Guns N' Roses. A giant ball of flames shot up during the end of the song, and Hetfield got confused and stood right above it. He suffered horrible third-degree burns and couldn't play guitar for weeks, but the tour carried on.
