Metallica’s original studio album, commonly called The Black Album, contains 12 songs.
The track list begins with “Enter Sandman” and ends with “The Struggle Within.” Between them are major songs such as “Sad but True,” “The Unforgiven,” “Wherever I May Roam,” and “Nothing Else Matters.”
The original vinyl presentation divided the 12 tracks 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 physical format of the 1991 release.
Expanded anniversary editions contain additional demos, live performances, and cover versions, so their track counts differ. The answer refers to the original studio album’s standard track listing, not later deluxe packages.
