A nice musical detail from the film, Inception.

If you’ve seen the movie, you know that a grainy recording of Edith Piaf singing “Non, Je Ne Regrette Rien” is used as a cue for the dreamers. You also know that while dreaming, time slows down.

With that in mind, it turns out that the throbbing musical sting we hear throughout the movie is that original piece of music… slowed down.
