Which chart did Metallica top for the first time with its 1991 self-titled album?

Metallica first topped the Billboard 200 with its 1991 self-titled album.

The Billboard 200 ranks albums and equivalent releases in the United States. Metallica debuted at number one, making it the band's first album to reach the top of that chart.

The record's success was not limited to the United States. It also debuted at number one in nine other countries, including the United Kingdom, Australia, Canada, Germany, New Zealand, Norway, the Netherlands, Sweden, and Switzerland.

The Billboard 200 should not be confused with the Billboard Hot 100, which ranks individual songs. “Enter Sandman,” the album's lead single, reached number 16 on the Hot 100, while the album itself reached number one on the Billboard 200.
