How many countries did Metallica's The Black Album top at number one?

Metallica's The Black Album topped the album chart in ten countries.

Its international success matched its breakthrough in the United States, where it became Metallica's first number-one album. It also reached number one in markets including the United Kingdom, Australia, Canada, Germany, New Zealand, Norway, the Netherlands, Sweden, and Switzerland.

The record's global performance showed that its appeal extended beyond the band's established metal audience. Its polished production and more direct songwriting connected with listeners in several major music markets while retaining the band's heavy identity.

The number ten refers to countries where the album reached the top position, not the number of countries where it charted. It also should not be confused with the album's five commercial singles or its four consecutive weeks at number one on the Billboard 200.
