I'm completely ignorant of what zouk and kizomba are. They're the name of dances but I assume it's a reference to the rhythm? In the first song, Divises, it's about undulating the mid body gently and slow turns. The melody is very prominent so that should be what the body responds to most. In the second, Divises Remix Kizomba, with the strong rhythm and subordinate melody, it's about moving the hips and legs with steps. For the most part, the upper body is still.
