The original album version of Metallica, known as The Black Album, contains 12 tracks.
The sequence begins with “Enter Sandman” and ends with “The Struggle Within.” Other familiar songs in the sequence include “Sad but True,” “The Unforgiven,” “Wherever I May Roam,” “Nothing Else Matters,” and “Of Wolf and Man.” The album’s total running time is about 62 minutes and 40 seconds.
The original vinyl configuration divided the 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. This layout reflected the album’s release as a double LP even though the album was also issued on CD and cassette.
Later deluxe editions added demos, live recordings, interviews, and other material. Those expanded sets can contain many more than 12 tracks, but they do not change the number on the original studio album. The distinction is important when comparing editions.
