Metallica's original 1991 album contains 12 standard tracks.
The sequence begins with "Enter Sandman" and ends with "The Struggle Within." Other tracks include "Sad but True," "The Unforgiven," "Nothing Else Matters," and "My Friend of Misery."
The standard edition has a total running time of 62 minutes and 31 seconds. A Japanese edition added "So What," a cover of a song by the Anti-Nowhere League, as a bonus track, making that edition longer than the standard release.
The album was also issued on vinyl in four sides, with three tracks assigned to each side. This format divided the 12-song sequence evenly and reflected the physical constraints of the era's records.
