Metallica's original studio album, commonly known as The Black Album, contains 12 tracks.
The sequence begins with “Enter Sandman” and ends with “The Struggle Within.” Between them are major songs including “Sad but True,” “The Unforgiven,” “Wherever I May Roam,” and “Nothing Else Matters.”
The album's compact twelve-song program helped make it accessible to a broad audience while still covering several sides of the band's style. It includes aggressive material, mid-tempo heavy songs, and the widely recognized power ballad “Nothing Else Matters.”
Expanded anniversary editions contain much more material, including demos, live performances, and alternate recordings. Those deluxe releases should not be confused with the original 1991 studio album, whose standard track list has twelve songs.
