To answer the original question, I would say that musical snobbery is denigrating other people's taste in music. It doesn't matter if we all share each other's taste or not.....heavens, the world would be a dull place indeed if we all liked the same things, whether it be music, books, films, anything at all......but just because someone doesn't share your taste doesn't make them better or lesser than you.

I like many music genres although rap music leaves me cold, as does doof-doof head banging music, and modern so-called 'country' music does nothing for me at all - but you may like them, and that's quite OK.

Now I am off to play my ukulele.
