Explanation

The structure of the sentence alerts us that it will describe a kind of contradiction or paradox: music lovers want something, but when they get what they want, they discover some cause for dissatisfaction.

Among the answer choices, the only two words that produce such a paradox are “flawlessness” and “wrong” — the music lovers long for flawlessness but are unsatisfied with a world in which nothing is wrong.

Thus, the correct answer is flawlessness (Choice C) and wrong (Choice D).
