Ohrwurm is a fantastic German word that literally translates to "ear worm" (Ohr = ear, Wurm = worm). It's the perfect term for a catchy song that gets stuck in your head, playing on a loop.
This word is so descriptive that it has been adopted into English, but its German roots make it a fun word to learn. In the song, Apache 207 sings that his partner has an Ohrwurm from one of his melodies, humming it long after he sang it to her, which adds to the track's romantic and intimate atmosphere.
This song is all about wanting a perfect moment to last forever. Apache 207 starts with some intense imagery: he's lying next to someone, feeling her breath and hearing his own heart beat, but describes his pillow as being made of scars and his blanket of pain: "Ein Kopfkissen aus Narben / Und eine Bettdecke aus Schmerz" (A pillow of scars / And a blanket of pain). It suggests that even though things are good now, there's a difficult past.
But the mood quickly shifts to something incredibly sweet. He describes her humming a song he sang to her while she was asleep in his arms. He finds her slightly off-key singing perfect and repeats over and over, "Ich will nie mehr weg von hier" (I never want to leave here). The song then jumps between these beautiful scenes: driving at night in a convertible while she sleeps, being on vacation in Santorini, and seeing her red lipstick on his cocktail glass. It's a snapshot of a perfect, peaceful time, and he's practically begging for it not to end.
