Monnaye comes from the verb monnayer, which means 'to monetize' or 'to turn into money'. It's a less common verb than simply 'payer' (to pay).
In the song, the line "Le bonheur se monnaye" (Happiness is monetized/paid for) is particularly striking. It suggests a cynical view where even happiness is something that can be bought or has a price, reflecting the song's themes of money, desire, and the pursuit of material wealth.
Get ready to groove with L.E.J and Youssoupha in "Milliards De Roses"! This song is all about wanting everything and refusing to choose between what seem like opposites. They're not interested in picking sides, declaring "On n'a pas envie de choisir / Y a ni mauvais film ni mauvais rôle" [We don't want to choose / There's no bad movie or bad role].
They want it all: "Milliards d'euros, milliards de roses" [Billions of euros, billions of roses] – the money and the beauty, the practical and the poetic. They even challenge the idea that money is just money, asking, "Pourquoi ne pas lui donner nous-mêmes un parfum de fleur?" [Why don't we give it a flower perfume ourselves?]. It's a fun, bold take on ambition, mixing dreams of wealth with a desire for an ideal life, even if it means finding "du pétrole sur les pétales" [oil on the petals].
