The lyrics to Fifty-Sixty tell, in personal and metaphorical manner, of a young model under the guidance of Andy Warhol, possibly inspired by real-life story of Edie Sedgwick.

The song ends with a reiteration of how she foolishly believed Andy thought that she was the most beautiful model of all.

The music video starts with Alizée and her friends talking and walking in the stairs of a building.

Later, they enter an apartment and Alizée puts on a vinyl which has the cover of the "Mademoiselle Juliette" single on it.

According to Alizée, a member of her crew had distributed clips of the song onto the Internet without permission for the label.

She also stated that fans complained about the leaked version of the song, even though it wasn't fully finished and produced.
