Master Of Puppets by Metallica

"Master of Puppets" is a song by the American heavy metal band Metallica, released in France on July 2, 1986 as the only single from the band's 1986 studio album of the same name. It was also issued as a promo single in the US by Elektra Records. The song was recorded during October–December 1985 at Sweet Silence Studios in Copenhagen, Denmark.

The song, as lead singer James Hetfield explained, "deals pretty much with drugs. How things get switched around, instead of you controlling what you're taking and doing, it's drugs controlling you." The song was bassist Cliff Burton's favorite song on the album, as quoted when the album was released. It remains the most popular Metallica song of all time.
