This was movie about young people, who danced in club. I remember man with dark glasses - singer. He sings (at the end song): "No! No! No! No!" (this is quite dynamic track). Probably 90's years. There were unprofessional dancers. This isn't "Step Up", rather older movie (before 2000). Comedy probably. I remember only one white singer (not Afro-American). Genre of music - dynamic, pop. This was movie about young people, who danced in club. I remember man with dark glasses - singer. He sings (at the end song): "No! No! No! No!" (this is quite dynamic track). At the end song - changed action. This isn't rather music movie, but comedy or something similar. American movie. Please about suppositions with this movie.

Movie was probably similar, but song is milder. "No! No! No!" - singer sings slow, repeats twice words and end. 100% - singer is white man. 90% - he has dark sunglasses. There weren't any kids - if I have a good memory. I watched this movie in 1996-1998 (probably). This don't was movie about dance. I remember that moment in club could be only bonus. Start of film probably.
