My theory about why Alizée might by angry goes back to how the single was leaked before release. I'm fuzzy on the details from back then, it was before my time and not something I've dug into. I guess Fifty-Sixty was going to be the first single for Psychedelices but after it leaked they switched to Mademoiselle Juliette. Just guessing that maybe this leaked clip has some connection to the leaked single way back when.
