A woman is playing music on a stereo in a busy city.  Another woman is standing on the sidewalk with headphones.  They both smile at each other as they groove to the music.  The woman picks up the stereo and starts walking.  The other woman follows her on the same sidewalk.  They walk together holding the stereo.  A man in a red shirt starts dancing next to a car with another woman.  They join the woman walking with the stereo in her hand.  Several other people join them as they walk and dance to the music.  All the people break into a synchronized dance right on the street.
