If that is your intention ie. insulation and a covering , then use rubber strips or a non hardening caulk (silicone ?) between the studs and the sheetrock no matter what type of sheetrock , vapor barrier and insulation that you use . The object is to stop the sound transmission through the material . This is especially important in the ceiling with your application .
I would suggest using styrofoam insulation . You can get various sizes and thickness's at Home Depot , it won't hold water like fiberglass or some other forms of insulation , it is a denser material that works better for sound transmission abatement and you get a higher insulating value per inch .
Good luck.
