The record also continues to hold the record as the best-selling album in Nielsen Music history with 16.83 million copies sold.

Billboard reports that Metallica’s 1991 self-titled album, also known as the “Black Album,” has officially become the fourth record in history to spend 500 non-consecutive weeks on the US Billboard 200 album chart.

Other three records that reached this number since the chart began publishing in 1956 are:

Pink Floyd’s “The Dark Side of the Moon” – which also holds the record for the most weeks on the chart:

937 – as well as Bob Marley and The Wailers’ “Legend: The Best of Bob Marley and The Wailers” with 539 weeks, and Journey’s “Greatest Hits,” also with 539 weeks.

“Black Album” marked Metallica’s first-ever No. 1 on the Billboard 200 when it debuted atop the list back in August 1991.

The record initially spent four weeks at No. 1 and marked the first of so far six chart-toppers for the band.

The record also continues to hold the record as the best-selling album in Nielsen Music history with 16.83 million copies sold in the US since Nielsen began tracking data in 1991.
