Nuit Blanche captures the thrill of an all-night party where music, laughter, and summer heat make everyone forget about tomorrow. The singer revels in the fantastique atmosphere, shouting « Vive la fête » as guests refuse to slow down. It is a celebration of excess: no one wants soup or coffee, only more dancing and shared madness. The lyrics paint vivid scenes of flashing lights, unstoppable beats, and the magnetic pull of good company.
Yet beneath the glitter, the song hints at the morning after. Fatigue creeps in, regrets surface, and the fun starts to feel like wading through a swamp. By holding his head in his hands, the narrator wonders why he threw the party at all. This contrast turns the track into both a love letter and a cautionary tale about hedonism: partying can feel heroic, but every nuit blanche (sleepless night) eventually asks you to pay the price.
