Metallica's 1991 album, The Black Album, contains 12 main tracks.
The standard track listing begins with “Enter Sandman” and ends with “The Struggle Within.” Between them are songs including “Sad but True,” “The Unforgiven,” “Wherever I May Roam,” “Nothing Else Matters,” and “My Friend of Misery.” Together, the standard edition runs for 62 minutes and 31 seconds.
The Japanese edition added “So What,” a cover of a song by the punk band Anti-Nowhere League. That bonus track can cause confusion when listeners count the album's songs, because it makes the Japanese edition a 13-track release while the standard album remains a 12-track record.
Vinyl editions also divide the music differently from a single CD. The 12 standard tracks are spread across four sides, with three tracks on each side. The track count in this question refers to the regular album sequence, not bonus material or later box-set extras.
