I know this may sound strange but the music box in the episode "Survivors" always bothered me for how unsettling it was. I get music stuck in my frequently but I can't imagine the amount of torment Troi had to endure hearing that same melody endlessly repeat "in perfect clarity from beginning to end". Not only was the box an effective tool to keep Troi from sensing what Kevin Uxbridge really was, but it also managed to nearly drive her into insanity. Did this bother anyone else? I love the episode but I have a hard time enduring those Troi scenes without relating to the pain she's going through. Oh, and now I hate music boxes.
