To understand lyrics by Stromae you need to check the French version of the lyrics on genius.com as there are explanations added by friendly native speakers. The texts are full of connotation, context, idioms - I’ve not seen anything like it in any modern song. It’s very cumbersome to translate all of that but I found it rewarding. Especially the lyrics of Papaoutai and Bâtard are masterpieces.
