Муляжи (mulyazhi) literally translates to "dummies" or "mannequins", like the ones you see in a store window. It's a very uncommon and visually striking word to find in a pop song.
In this track, NILETTO uses it as a powerful metaphor for a failed relationship, singing "Что от нас лишь муляжи" (That only dummies are left of us). He's saying their love has become hollow and lifeless—an imitation that looks real on the outside but is empty on the inside, capturing a deep sense of heartbreak.
NILETTO knows a breakup is coming, but he still asks for one simple, decent gesture: "Просто так, по-людски обними меня" ("Just like that, like a decent human being, hug me"). The Russian phrase по-людски literally means "in a human way," basically asking his partner not to act cold or bitter, even though she is about to walk out "как в песне Someone like you" ("like in the song 'Someone Like You'"). He borrows Adele's famous breakup title to set the scene, knowing full well that they are down to fake replicas of themselves ("от нас лишь муляжи" ["only dummies/fakes are left of us"]) and have run out of shared futures ("без перспектив" ["without prospects"]).
Instead of quietly sulking in a corner, he channels that mess into club energy. He fires off lines like "подрываю танцпол" ("I blow up the dance floor") and compares his mood to a full-blown typhoon. There is a wild swing between feeling fine right now—"с кайфом" ("with a buzz / having a blast")—and the harsh reality check that hits in the very next breath: "Мне завтра очень грустно без тебя" ("Tomorrow I'll be very sad without you"). He is tearing through the heartbreak at top speed ("на форсаже" ["on afterburner"]), mixing cinematic drama with the blunt realization that he just could not make love last forever.
