Which band did Metallica cover on the Japanese edition of The Black Album?

The Japanese edition of Metallica's The Black Album included “So What,” a cover by Anti-Nowhere League. It appeared as track 13, after the 12-song standard album.

“So What” was not part of the regular international track listing. The standard edition ends with “The Struggle Within,” while the Japanese release adds the bonus track and extends the total running time to 65 minutes and 39 seconds.

The cover connects Metallica with the British punk band Anti-Nowhere League. The songwriting credits for the song belong to Chris Exall, Clive Blake, Nick Culmer, and Djahanshah Aghssa, the members credited for the original composition.

This bonus track is easy to confuse with songs by artists associated with Metallica's early influences, such as Diamond Head. Diamond Head influenced Metallica, but it was Anti-Nowhere League whose song appeared as the Japanese-edition bonus track.
