A dark-haired man is singing in the room,on several TV,or computer screens,a girl is dancing and he is singing for her the whole time and there is no one else but them.I think he might have been a DJ,but I remember too little just the melody bit into my head,but I still can't find the video,neither by humming nor by key words,I think it was a bit of a dance track because his voice harmonized perfectly with the woman's dance on the screen.
