Song: Master of Puppets Artist: Metallica Album: Master of Puppets (1986) Genre: Thrash Metal / Heavy Metal Length: 8:36 minutes “Master of Puppets” is one of Metallica’s most iconic and powerful songs. With crushing guitar riffs, explosive drums, and intense vocals, it dives deep into themes of control and addiction — portraying a person being manipulated like a puppet by a powerful force (like drugs or inner demons). The energy and aggression in the track make it a perfect anthem for intense workout sessions and pushing your physical limits.
