Master of Puppets is the second song off Metallica's 1986 album Master of Puppets. The song, following the theme of control with the rest of the album, discusses drugs and their effects. Addiction, the master referenced in the title, narrates the song, testifying to the destruction that comes from being under the control of drugs. James Hetfield explained the song "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.
