For Whom the Bell Tolls

Hetfield, Ulrich and Burton share the credit. Burton's bass intro was first played in 1979 with his earlier band Agents of Misfortune. The title and subject come from Ernest Hemingway's 1940 novel, in particular an airstrike in Chapter 27. The bell was an anvil struck by Ulrich, together with a sound-effects bell, and the bass intro was built from three tracks with a wah pedal. A promo edit runs 3:59, against 5:11 on the album. It is 3x Platinum in the United States, and Rolling Stone ranks it 39 on its 2023 list of the 100 greatest heavy metal songs. It appears on S&M and S&M2, and DJ Spooky remixed it as The Irony of it All for the Spawn soundtrack. It was released as a promotional single with an edited version on the A-side and the full album version on the B-side. Burton's intro was first played during a 12-minute jam at a battle of the bands in 1979. DJ Spooky's remix was later retitled Haven't Heard It Yet Mix when Metallica put it on the single for The Memory Remains. By March 2018 it ranked fifth on the band's live performance count.
