I used to listen a lot of times this song on youtube around two years ago.
In the video there was a girl doing stuff, I remember she laid down in bed. Music was kind of slow and calm, with synths. The lyrics where short and hard to understand because of the effects, but it was a girl. I don't know french but maybe they sang "dessein" or "dassein" or something I liked to think about as "desire".
The video was kind of sexy. Does anybody know which song is? It's driving me crazy!
