Sachet, chantez!

Three days of rain outside and anxiety at work is doing nothing for my bad mood. Let's try a poll!

What are your favourite songs with lyrics either partially or entirely in French?

( My picks, hidden so as not to prejudice anyone )

Update: I almost said "favourite pop songs" but then decided to leave out the qualifier. And I'm glad I did, because I'm really enjoying everyone's classy choices. But don't be intimidated; as bunj's answer shows, even execrable American hipster "French" qualifies!
