Metallica’s 1991 self-titled album, commonly called The Black Album, contains 12 tracks.
The sequence opens with “Enter Sandman” and closes with “The Struggle Within.” Between them are well-known songs including “Sad but True,” “Holier Than Thou,” “The Unforgiven,” “Wherever I May Roam,” “Don’t Tread on Me,” and “Nothing Else Matters.”
The original vinyl configuration divided the twelve songs across four sides: tracks 1–3 appeared on Side A, tracks 4–6 on Side B, tracks 7–9 on Side C, and tracks 10–12 on Side D. That arrangement reflects the album’s original physical-release format.
The album’s twelve-song program includes both aggressive metal tracks and more accessible material. That balance helped Metallica reach listeners beyond its established thrash-metal audience.
