Les 3 Points De La Victoire Au Buzzer Du Mvp
Je n'ai rien fait d'autre que mon travail, Mr Simba
Les plus belles roses poussent dans la merde
This swahili woman showed me what a family was
Le grand frère de la street que tu n'as jamais eu
Je n'ai rien fait d'autre que mon travail, Mr Simba...
Les Plus Belles Roses Poussent Dans La Merde
This Swahili Woman Showed Me What A Family Was
La division des deux stars du rap français
Les quartiers ont craché à la gueule de ma fidélité
Le coeur est le muscle qui pompe le plus de sang
Abraham, Schwarzenegger et leurs femmes de ménage
