The movie that inspired Ayu for her Free&easy theme is a french movie by Luc Besson : "The messenger : Joan of Arc" (i'm not sure of the american title, in France it was simply called "Jeanne d'Arc").
The music you can hear in the intro of the song is an excerpt from the movie's OST, titled "No amen", by Eric Serra.
Luc Besson is famous for movies like : "Le grand bleu", "Leon" (american title is : "The professional"), "Le 5° element" ("the fifth element", starring Bruce Willis and Milla Jovovich).
