Metallica’s self-titled 1991 album, commonly referred to as the ‘Black Album,’ is the No. 178 album on this week’s Billboard 200 chart. That chart placement ensures that the ‘Black Album’ reached a sales milestone by spending its 750th total week on the Billboard 200. It is only the fourth album in music history to reach that impressive mark of chart longevity, joining Pink Floyd’s The Dark Side Of The Moon (990 total weeks), Bob Marley’s Legend (843 total weeks) and Journey’s Greatest Hits (813 total weeks). Metallica is one of the most commercially successful records of all time, becoming the heavy metal legend’s first No. 1 album in over 10 countries worldwide, including an impressive four-week run at No. 1 in the U.S. The Grammy-winning, 16x-platinum ‘Black Album’ is the best-selling album in the history of Nielsen SoundScan, outselling all releases in every genre over the past 33 years.
