The reason people don't like a particular musical genre has nothing to do with how they feel about the good songs in the genre. It's because they never hear the good songs.
Every genre is a mountain of coal with a few diamonds scattered and buried inside. People who don't like a particular genre are put off by the crappy songs. . . the coal.
It has to be this way.
If there were mountains of diamonds, then diamonds would be looked upon in the same way we look upon coal. In fact, if diamonds were as plentiful as coal we would burn them in our furnaces.
That is the nature of genres.
