This song is living proof that whatever you try to do, if you execute it well, the rest can take care of itself. Serge didn't even bother writing a song (this is just an arrangement of Chopin's prelude in E minor). But the song is excellent, and stands up to (at least several hundred) repeated listens. There's a slow, jerky beat, and a heavy bassline. Birkin's delicate vocal works well with this backing, and the whole thing has a very hip feel.
