This topic proved quite popular on another site I frequent, so I wonder if it will appeal here.

It's the opposite of 'guilty pleasures', where you admit liking a singer/performer/song/genre/track that is conventionally thought to be tacky or trashy or otherwise without merit.

A 'defiant dislike' is your chance to announce that even though a singer/performer/song/genre/track (or whatever) is widely acclaimed & almost thought of as beyond criticism, you cannot stand it/them.

Any offers ?

Personally I cannot abide Joan Baez or Billy Bragg.
