Five of Metallica's Black Album singles charted on the U.S. Billboard Hot 100.
The five were “Enter Sandman,” “The Unforgiven,” “Nothing Else Matters,” “Wherever I May Roam,” and “Sad but True.” Their appearance on the mainstream singles chart illustrated how widely the album reached beyond heavy-metal radio and specialist audiences.
“Enter Sandman” was the highest-profile early breakthrough, peaking at number 16 on the Hot 100. “Nothing Else Matters” later became one of the band's best-known international songs, while the other three singles also contributed to the album's long commercial life.
This total is sometimes confused with the number of songs on the standard album, which was 12, or with the number of major music videos associated with the record. It also refers to singles from the original album campaign, not every later promotional release or anniversary-edition track. The five-song count is therefore a specific charting statistic for the Black Album era.
