"Die, Die My Darling" is one of the Misfits' most iconic songs, first released as a single in 1984 on Glenn Danzig's Plan 9 Records, a posthumous release following the band's initial breakup. The title is directly lifted from the 1965 British horror film Fanatic (released as Die! Die! My Darling! in the U.S.), a common practice in the band's horror-punk tradition of turning B-movie titles into succinct, visceral punk anthems. Musically, the song is a quintessential example of the Misfits' style during the Glenn Danzig era, characterized by raw, fast-paced hardcore energy combined with a catchy, almost '50s rock-and-roll-inspired melody. The track is notable for its driving tempo, propulsive drumming, and the heavy, down-stroked guitar work from Doyle. Danzig's vocals are delivered with his signature, darkly theatrical croon, making the macabre lyrics both frightening and highly memorable. Lyrically, the song is stark and aggressive, taking the form of a malevolent farewell from a killer to his victim, reflecting themes of ultimate, fatal obsession. The chorus, "Die, die, die my darling / Don't utter a single word / Just shut your pretty eyes / I'll be seeing you again / Yeah I'll be seeing you in hell," is a darkly romantic chant that cemented the song's status as a horror-punk classic. An interesting production detail of the song is the distinct, high-pitched, almost electronic sound effect heard throughout the track, which some fans speculate is meant to represent a heart monitor or some other ominous machine. The single's artwork is derived from a 1953 issue of the comic book Chamber of Chills. The song's enduring popularity was later boosted significantly by a prominent cover version released by the band Metallica in 1998.
