Diluviennes comes from "diluvien," meaning "diluvian" or "flood-like." It's a strong, evocative adjective that you don't encounter in everyday conversation or many songs.
In the song, Amir sings, "Pour des nuits diluviennes" (For torrential nights). He uses this word to describe nights filled with an overwhelming intensity of emotions, likening them to a powerful, all-encompassing flood. This poetic imagery makes the word particularly striking and memorable.
In “Longtemps,” Amir celebrates a love so powerful that nothing is off-limits. He begs to carry his partner’s troubles, dance with her joys, and even brave torrential nights together. From tattooing their story on his arm to walking the streets bare just to warm her, he declares her his smile, his lucky card, and the single certainty in a world gone mad.
The chorus zooms in on one simple wish: may this love last a very long time—a lifetime, maybe a hundred years—until their eyes finally close. Amir dreams of forgetting everything, even his own name, as long as her skin is against his. Logic can knock on the door all it wants; the couple would rather stay inside their shared dream, where passion, pain, laughter, and hope fuse into one endless embrace.
