Walou is a slang term of Arabic origin, commonly used in French to mean "nothing" or "zilch". It's a more informal and emphatic way to say rien.
In the song, the artist uses walou to dismiss the threats and jealousy of others, stating that their attempts to cause trouble will amount to "nothing" (y aura walou). This word adds a touch of street credibility and defiance to the lyrics, making it memorable and culturally interesting.
This remix of Emkal's "J'la connais" adds a verse from Lynda, turning a one-sided love song into a back-and-forth between two voices defending the same relationship.
Emkal sings about being head over heels for a woman despite everyone around them trying to stir up trouble. Jealous friends and rumor-spreaders ("les jaloux", "les mythos") keep trying to break the couple apart, but he brushes them off — he knows the truth about who she is, and no outsider's opinion changes that.
The chorus is a shared promise: "on restera soudés" (we'll stay united). No matter how much gossip circulates, the two of them plan to stick together, and Emkal even looks ahead to a future with a child together.
Lynda's added verse mirrors the same idea from her side, swapping "cette fille" for "ce mec" — she's just as certain about him as he is about her, and just as unbothered by the people trying to come between them.
