Oseille is a French slang term for "money." While its literal meaning is "sorrel" (a type of herb), in this context, it's used colloquially to refer to cash or earnings.
In the song, Kery James uses it in phrases like "Faire ton propre oseille" (Make your own money), emphasizing self-sufficiency and earning an honest living, contrasting it with illicit activities. It's an interesting word choice because it's not a formal term for money, making it more engaging and reflective of everyday street language.
Je Peux drops us right into a lively conversation between French rap icon Kery James and his young cousin Noumouké. Over a smooth, reflective beat, the older voice urges his “p’tit frère” to ditch street violence, open the right windows in life, and believe that he can become absolutely anything — “astronaute ou baveux” (astronaut or lawyer). The chorus, “Je sais que je peux” (I know I can), pulses like a mantra of self-belief, turning the grey walls of the housing projects into a canvas for huge, sun-lit dreams.
But the track is no one-way lecture. Noumouké pushes back, revealing the anger and temptation that stalk young people in the banlieues, yet still echoing the same core truth: choices are powerful. Their back-and-forth paints two possible futures: one ruled by quick money and territorial pride, the other by education, hard work, and long-term vision. The message is crystal clear: no matter the obstacles, you hold the steering wheel of your destiny. Part motivational anthem, part raw snapshot of French suburban life, Je Peux invites every listener — including English learners — to repeat the words I know I can and make them real.
