“Belly fat in the bio bin/The penis now sees the sun again.” This soon-to-be-immortal couplet comes from “Zick Zack,” the hilarious plastic-surgery send-up and single from Zeit. Given the decade-long gap between Rammstein’s untitled 2019 album and its predecessor Liebe ist für alle da, the relatively quick appearance of their eighth record comes as quite a surprise. Clearly, the German industrial overlords took advantage of the enforced downtime every touring artist was saddled with during pandemic lockdown and emerged with their famous sense of humor intact. Zeit (German for “time”) boasts plaintive yet soaring piano ballads (“Schwarz,” the title track), odes to big boobs (“Dicke Titten”), and even a raucous cock-rock-style banger in “OK.”
