6. "For Whom the Bell Tolls"
Many people probably assume that the guys in Metallica don't sit around reading Ernest Hemingway books in their spare time, but someone in the group obviously picked up his 1940 classic For Whom the Bell Tolls before writing this song with the same title. The lyrics are directly inspired by a section of the book where soliders in the Spanish American War are gunned down on a hill. It's one of the standout tracks on Metallica's 1984 disc Ride the Lightning.
