If they don't seem enthusiastic/attracted by the music and looks then I'd put 'Panty Lies' on loud+repeat and lock them inside the room until they drown and choke in their own vomit which will sure taste like shit just like their taste in music, anyway, they'll be used to the taste for sure, so I'd have to get in and hit them in the head with a open F sharp tuned jazzmaster until they bleed and die.
