The fifth and final single released from Metallica’s seminal self-titled album, “Sad But True” is about a person’s darker side taking control.

Influenced by the 1978 horror film Magic, starring Anthony Hopkins, the song is a monologue justifying the existence of this darker side, which in the film is symbolized by a foul-mouthed ventriloquist’s dummy.

The song has been interpreted as an allusion to addiction, a struggle Hetfield has been open about, having previously entered rehab for “alcohol and other addictions”—another being chocolate.
