While looking through this thread, I thought of another pet peeve of mine.
People who reject whole genre's because they simply didn't like one, or two songs, or just hate the genre's out of principal. Those guys are idiots, pure and simple, because It's just limiting yourself at the end of the day, and what your ears can hear.
Yes, we all have our own preferences, but when there is such a treasure trove of great music, and with the advent of the great interwebs making it easier than ever before to find new music, there's going to be at least one song, or artist that you enjoy in the genre's that you don't normally listen to. For example, I never thought I would like Punk Rock, but I have found a few artists, and songs that I like from that kind of music, after exploring the genre, and what it can offer me.
Anthony Fantano (of the Needledrop) has also touched up on this subject in a recent vid.
So yeah, expand your horizons kiddies, go out of your comfort zone. Ignore stereotypes, and Listen to rap, even if you hate the genre, or listen to some hard hitting electronica if you think electronic music isn't talented. There's bound to be something you would like, even if it does require a little digging around.
So yeah, explore your dislikes, and maybe you can appreciate music a lot more, and then who knows, maybe you might find your favourite artist in those genres.
