The strange title of this album is in 14th century French, and means this devilish song. It comes from the last song of the collection, where the poet complains about a song that stays with him, even though all else disappears. I cannot explain this in any other way than a complaint about an earworm.
Or maybe it is the other way around: he loses all, because of this devilish song that is every where. Judge yourself:
If I have lost all that which was my own
It is not because of any wrong or shortcoming on my part
but it is because of this devilish song
which holds sway in this land.
Ah, the power of music.
