I'm not so sure. If you play death metal to people who distinctly do not like metal, they will tell you it all sounds the same, that it's just noise. The next metalhead to swing by can lament for hours on the compositional genius of Children of Bodom, but will ensure you all hiphop is a long string of meaningless profanity. Don't even bring the avantgarde jazz enthusiasts in. And so on.

What I'm getting at is that any musical genre will be difficult at first. And I don't mean just listening to a lot, but actually understand it.
