Well, I would not list Celine Dion as my favourite either, hehehe...
Probably I am not really qualified to give an opinion on a " favourite " . I do not listen to enough Quebec music. The only songs I am really exposed to are the ones I am exposed to on the yearly Juno Awards Album (read: Canadian Music Awards). That, and I have never spoken French well enough to understand the music. So, it would rather be like someone who does not speak French, German or Italian trying to rate opera. But, I do rather like the sound of Lynda Lemay's J'Vien Bien T'Aimer.
