Manigancés comes from the verb manigancer, which means to scheme, plot, or orchestrate something, often with a slightly negative or cunning connotation. It's not an everyday word, making it more interesting and memorable.
In the context of the song, the line "Les plans sont toujours bien manigancés" (The plans are always well orchestrated/manipulated) suggests that the speaker's actions and strategies are carefully thought out and executed, implying a level of street smarts and control over their environment.
"Chaque Jour" is Landy's boast track with Leto and Rsko, built around the phrase "every day" (chaque jour). Each verse lists what a day in his world looks like: stacking cash, carrying a gun for safety, staying sharp against rivals, and moving fast through Paris nightlife. The hook repeats "chaque jour" to show this lifestyle never lets up — it's a daily routine, not a one-time flex.
The lyrics lean on French rap slang and wordplay (nicknames, brand references, playful rhymes), so the tone is confident and a little humorous rather than serious. It's a song about staying on guard and staying rich, day after day.
