why should i like bad music?

I don't think there is such a thing as "bad music."

Sure, there is music you don't like, poorly executed music, music you don't understand, there are people you don't like who make music, genres of "noise," music you are embarrased to admit you that you listen to, music in complex time signatures that you can't dance to, screaming, poorly recorded, formulaic, overproduced, scary, silly, unfinished, boring, ear wormy............

But, none of that is "bad." Bad music would imply harm, psychological torture, physical sickness, not just unappealing but harmful. People are harmful, music is not.

It's a made up ratio, but i'd say music is a 15 to 1 ratio. For every 1 thing you like, there are 15 things you don't. That's not bad. That's just you. Your distaste should not translate to other people.  Some people don't have the time, energy, desire, to experience what they don't like in search of a moment of enjoyment. Some people think being a musician is not a valid job. I would argue that a musician is the real life embodiment of the political spectrum. Someone who must compromise their own likes and desires with the world at large to reach a stable relationship. Musicians must play what you say you want, even if they themselves don't like it, and even when it turns out that you didn't really want it. If you abandon them, they must keep going in seach of a new patron.

Some people don't like or think of music as an art form. For some people, music is the disposable paper plate of on the go entertainment. Yet, it seems wrong to deny the lovers of music their pleasure as well. If it's all about money we all lose, but if it's not about money at all we all still lose.

Art and science are two of the many things that don't mesh well with market based capitalism. They require a large degree of blind investment and an understanding of the small but vital return on that investment. An idea is only as powerful or good as the people who turn that idea into a reality, and a lot of people favor immediate pleasure over philosophical investigation.

There is no such thing as bad music, only music that you don't like. That's my opinion, for what it's worth.

Cheers
