“Nothing Else Matters” by Metallica, was released in 1992 as the third single from their self-titled fifth studio album, Metallica. The song peaked at number 11 on the Billboard Mainstream Rock Tracks chart, number 6 on the UK Singles Chart, number 1 in Denmark, and reached the top ten on many other European charts. “Nothing Else Matters” was featured as a playable track in the music video game Guitar Hero: Metallica. Recognized as one of Metallica’s best known and most popular songs, the power ballad has become a staple in live performances.
Metallica fans might have been confused when the band released Nothing Else Matters . A touchy-feely ballad that front man James Hetfield had written about missing his then-girlfriend Kristen Martinez while on tour, the song was a far cry from the war’n ’lightning imagery that had dominated Metallica’s past decade. But for fans who were paying attention, the song was the next logical step in the band’s progression.
It is definitely one of my all time favourites.
