Five commercial singles promoted Metallica’s 1991 self-titled album, commonly called The Black Album.
The singles were “Enter Sandman,” “The Unforgiven,” “Nothing Else Matters,” “Wherever I May Roam,” and “Sad but True.” They appeared over a period stretching from July 1991 into February 1993, helping the album remain visible well beyond its initial release.
“Enter Sandman” was the lead single, while “The Unforgiven” followed it later in 1991. “Nothing Else Matters” demonstrated the band’s ability to reach listeners beyond traditional heavy metal audiences, and “Wherever I May Roam” and “Sad but True” reinforced the album’s radio presence.
“Don’t Tread on Me” was sent to rock radio but did not receive a commercial single release. That distinction sometimes causes confusion when people count the album’s promoted songs. The five official commercial singles all charted on the Billboard Hot 100.
