Melody loved dancing, especially dances from her childhood.  I remember many days in my childhood where Mom would put on one of her old records and would show me some of the old dances like The Mashed Potato, The Twist, The Pony, The Swim, etc.  She also loved all of those songs from that era as well, so she’d be singing along as she showed me her old dance moves.  It’s probably because of her childhood nostalgia that she loved the movie Hairspray (the original).
