Mojo is a fascinating word because it's a direct borrowing from English, often associated with a magical charm, spell, or a quality that brings success or good luck.
In Claire Laffut's song, it's used as an almost incantatory plea, "Mojo, mojo, Mojo, t'en va pas" (Mojo, mojo, Mojo, don't go away). This suggests the singer is addressing a mystical force or a feeling of irresistible allure that she doesn't want to lose, making it both mysterious and captivating.
Claire Laffut sings about the pull between two people that neither can resist. Their eyes give them away: "Nos yeux n'ont pas d'alibi" (our eyes have no alibi), and they are drawn together "comme deux aimants" (like two magnets). She shrugs it off with a repeated "Tant pis" (oh well), as if giving in were the only sensible answer.
The chorus is a plea to keep the spark alive: "Mojo, t'en va pas" (mojo, don't go away). In the bridge the attraction becomes a car swerving off course, "Déviation sur le bas-côté" (a detour onto the roadside), with "Deux souffles qui se cherchent" (two breaths seeking each other). It is a song about letting desire take the wheel.
