Metallica was creeping in on the metal watchlist when in 1986 they released their absolute voice of intent with "Master of Puppets". This title track is the second song on the shared name album. It is over 8 minutes long (8:26), and encompasses the enslaving power of drug addiction.

Singing the repeating verse of this song has become somehow a rite of passage to becoming a true metal head. This elemental song is most often found in the number one position on many greatest of all-time heavy metal charts.
