This has fast become one of my favorite songs. It’s called “On veut plus que de l’amour” and is sung by Natasha St-Pier as the closing track on her latest self-titled opus.
It’s the epitome of melancholy, yet unexpectedly comforting. I think I’ll let the lyrics speak for the rest.

On veut plus que de l’amour
on veut toucher au bonheur
On oublie que chaque jour qui passe est le meilleur
Mais le bonheur est si petit
qu’au bout du compte, il passe entre nos mains
qu’au bout du compte, il passe entre nos vies

And for the non-francophone inclined:
We all want more of love
We all want to touch happiness
We all forget that each day that passes is the best
But happiness is so short
That after all has been said and done, it slips between our fingers
That after all has been said and done, it passes between our lives
