Nothing Else Matters - Live In Rio de Janeiro, Brazil - September 19th, 2015

Band members James Hetfield, Lars Ulrich, and Kirk Hammett wrote this. According to Hetfield, he wrote the song about a girlfriend he once had, but when he looks back at it, he can't remember why he wrote it. Now, Metallica just considers it a song about their fans, because nothing else matters but their fans.

The orchestration in the song was arranged by Michael Kamen, who also conducted the San Francisco Symphony orchestra. This song appears on Metallica's 1999 live album S&M, which was recorded with the San Francisco Symphony orchestra.

James Hetfield has cited the band's constant touring as an inspiration for this song. They wrote pieces of the song on their tour bus and in numerous hotels.
