How long did Metallica's 1991 album Metallica stay at number one on the Billboard 200?

Metallica's 1991 album Metallica stayed at number one on the Billboard 200 for four consecutive weeks. It was the band's first album to top the US albums chart.

The record debuted at number one after selling 598,000 copies in its first US week. Its sustained performance was especially notable because the album did not depend on a single opening-week spike; continued sales were supported by several widely played singles and music videos.

The chart run helped establish Metallica as a mainstream international act. The album had begun as a deliberate change from the longer and more technically elaborate style of the band's first four records. Bob Rock's production emphasized a heavier, clearer, and more accessible presentation.

The album's later sales history was even more remarkable. It became the best-selling album of the Nielsen SoundScan era in the United States and eventually surpassed 20 million US units according to later RIAA certification reporting. Its four-week run was therefore an early sign of a much larger commercial legacy.
