The standard version of Metallica's 1991 album Metallica contains 12 tracks.
The sequence begins with “Enter Sandman” and ends with “The Struggle Within.” Between them are songs including “Sad but True,” “Holier Than Thou,” “The Unforgiven,” “Wherever I May Roam,” “Don't Tread on Me,” “Through the Never,” “Nothing Else Matters,” “Of Wolf and Man,” “The God That Failed,” and “My Friend of Misery.”
The album's songs vary considerably in mood and arrangement. The track list moves from arena-sized riffs to the acoustic opening of “Nothing Else Matters,” then closes with the intense “The Struggle Within.” The complete standard sequence runs for roughly an hour.
Some reissues and special editions add demos, live recordings, or other material. Those expanded editions should not be confused with the original standard album, whose core track count is 12.
