The popular choice can still be yours when you understand why you enjoy it.

Liking something that many people like is not a failure of taste. The suspicion comes from a fear of being predictable, which pushes people into performing preferences they do not hold. What makes a choice yours is not rarity but knowing what it does for you: the sound, the comfort, the memory attached, the particular thing it gets right. Ownership is a matter of reasons rather than obscurity.

Take something popular that you enjoy and say precisely what you enjoy about it. If the answer is specific, keep it happily. If there is no answer, that is worth knowing too, and it applies just as much to obscure tastes.
