Metallica's 'Black Album' has just set a new record! The album has become the first in SoundScan history to surpass 16 million records sold.

The Neilsen SoundScan system launched in 1991 and has become the go-to source to track record sales. According to the service, Metallica's 'Black Album' is the most purchased piece of music of the past 13 years, not just in metal, but all genres.

The record has spent a total of 307 weeks on the Billboard 200 chart, with 20 of those weeks having come in 2014. In the history of Billboard, the 'Black Album' is the third longest-charting studio album, only falling behind Pink Floyd's 'Dark Side of the Moon' and Carole King's 'Tapestry'. Metallica's 1991 release is also the sixth longest charting album of any kind in Billboard history.

In other Metallica news, the band just performed the '... And Justice for All' track 'Frayed Ends of Sanity' for the first time ever. As a part of their 'Metallica by Request' tour, the legendary thrash band headlined one of the most amazing metal bills ever put together. Slayer, Mastodon, Ghost and Gojira all opened for Metallica last night (May 28) for a phenomenal showcase in Helskini, Finland.

"We're going to have sit down and spin that one around for an hour or two," Metallica drummer Lars Ulrich recently told the Delaware County Daily Times of 'Frayed Ends of Sanity.' "We carry a rehearsal room with us wherever we go. Give us an hour and we can learn any song in our catalog. We like to make the setlist real wacky and change it up as much as possible, but in 2014 the fans are picking the songs." [via Blabbermouth]
