What is the longest track included in Guitar Hero: Metallica? “Mercyful Fate.”

The game’s longest included track is “Mercyful Fate,” an approximately 11-minute medley of songs by the Danish heavy-metal band Mercyful Fate. It is performed by Metallica and appears as one of the influential songs selected for the game’s soundtrack.

The medley is longer than better-known lengthy Metallica entries such as “Master of Puppets” and “One.” Its title can cause confusion because it refers both to the original band and to the Metallica recording that combines several Mercyful Fate songs. It is not simply a cover of one short standalone composition.

Mercyful Fate was an important influence on Metallica, and the band’s members helped secure material for the game. King Diamond participated in newly recorded masters of Mercyful Fate songs for the project, with “Evil” also appearing separately in the soundtrack. The medley’s unusual length makes it the clear answer when the complete game track list is compared.
