While the soundtrack to the 2007 Edith Piaf biography, La Vie en Rose (aka La Môme) -- which features a fantastic performance by Marion Cotillard as the Sparrow -- doesn't include only Piaf songs (that's only the first third), the rest of the album, filled out by pieces from the original score and versions of some of her songs ("Les Hiboux,""Mon Homme"), doesn't do a bad job of conveying the sentiments -- passion, agony, etc. -- of the film. Of course, if Edith Piaf is what you want, an actual Edith Piaf collection is in store, not this, but if you loved the movie, La Vie en Rose (or La Môme) isn't a bad option.
