Help with French song

Alright this is going to be the most vague description ever, but I'm getting pretty desperate but I heard it in the bar of a hotel I was staying in the other week and need to know.

It's an upbeat type of song, there's some horns in it. It's all in French, sung by a female. The chorus ends in the word "moi" I believe. And in the chorus there's a whole lot of: "ahhhhhh, ahhhhhh"

Please help me :'(

Very sorry about all of this. I know the feeling. It will be very tough, but what the hell here's a shot out of the dark.
