Metallica - Master Of Puppets

James Hetfield in Thrasher magazine: "'Master of Puppets' 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. Like, I went to a party here in San Francisco, there were all these freaks shooting up and geezin' and this other girl was real sick."

In an MTV Icon special, James Hetfield said that it wasn't until after this song was written that he realized it related to his alcoholism.
