Yeah, she picks some odd songs... but does them wonderfully in her own style. She's French, but if she would just enunciate the words a "little" better she'd be magnificent. But for singing in a tongue not her first language she does great. Her piano skills are excellent too. (I'm in no way taking a dig at her accent/language etc... I think French is the most beautiful language on earth).
Please, if you haven't already, check some of her covers. just follow the link above, she also does Cool Cat, Death On Two Legs, It's A Hard Life very well too. She has a very good ear for music I think.
