Spider & the Fly seems like a fitting title due to the harshness of the metaphor.
It seems as though he is the spider & the person he is singing to would be the fly. The fly is of course cautious of his actions. The spider is trying to trick the fly into going away with him... However, the metaphor could also be for a person who wants to be with someone, but that person doesn't want to be with them, so he offers them a grandness of sorts. He tries telling them that he'll take them away somewhere that's grand, however, he only has a hidden agenda of his own, just as the spider does to eat the fly...
