Rarité is a French loanword meaning 'rarity' or 'something rare'. It's an interesting choice in a German song, adding a touch of sophistication and uniqueness.
In the lyrics, Dardan sings, "Sonnentage Rarité" (Sunny days, rarity). He uses this word to convey that moments of happiness or 'sunny days' are scarce and precious in his current emotional state, highlighting the contrast with the drama and pain he's experiencing.
Dardan and Azet's "Vermisse" [Miss You] is a raw look at a relationship that's a constant push and pull. The singer is stuck in a loop, asking, "Wie kann es sein, dass ich dich vermisse?" [How can it be that I miss you?] even though it's "Immer Drama, bei Gott" [Always drama, by God]. It's clear there's a deep connection, as he describes her beauty: "Langes Haar, Balayage, deine Schönheit validé" [Long hair, balayage, your beauty validated].
But this isn't a simple love song. He admits, "Ich zeig' dir keine Liebe und mein Herz ist eine Schutzweste" [I don't show you love and my heart is a bulletproof vest]. He's torn between wanting her and his own self-preservation, even saying, "Ich muss an mich denken, bevor ich an uns denke" [I have to think of myself before I think of us]. It's a complicated story about missing someone who might not be good for you, and the struggle to let go when they still live "in mei'm Kopf" [in my head].
