Hmm. I really can't think of anything. When I was young, I used to be insufferably snobbish about music and deemed anything "popular" to be garbage just because. I don't hold to this view any more though, quite the opposite.

Oh wait, coffee! Not quite all the way to that "will only brew coffee from beans I grew and ground myself" stuff but as I can nowadays only drink that one, important cup of coffee in the morning, I'd like it to be something I actually enjoy and not just "ehh, it's fine". I've also sometimes come across coffee so vile that I couldn't drink it or even really call it coffee so yeah, a bit on the snobbish side with that one, I think.
