I like this Hungarian song! Going to ask my Hungarian friend if she know it. Oh yes, Edith Piaf is fantastic. Myself and my sisters husband have a fascination with classic songs in line with sort of a French and Italian tradition, mostly by female vocalists. I got inspired to trawl though my favourites list and find some artists you might like, even though it's mostly a shot in the dark.
I like pretty much everything with Marie Laforêt, for example this one.
Another of her songs with the same atmosphere is Aux Marches du Palais
and Je Voudrais Tant Que Tu Comprennes
. She has also made tracks with more go in them, for example D'Être á Vous, Sur le chemin des Andes (El condor pasa)
and Marie Douceur/Marie Colere
, a rendition of a famous Rolling Stones song. Check it out if you like.
If you have a soft spot for French, check out Jacques Brel, though he is more "Folk", perhaps apart from the song underneath here. He was Belgian (Flemish if my memory serves me right) and if you are to believe my old French teacher, drew even bigger crowds than Edith Piaf back in the day.
Of course there is also Serge Gainsbourg, but everyone knows him I think.
I'll just throw this in here too, from my sister language - Swedish, just because it is a good song hehe.
