You use the word “all,” not I. However, I am not so blind as to see how people elevate their own tastes, like its dogma, and OCP “style,” whatever that means, is an heretical taste. I also think there is a blindness that if all music became chant and organ that all “real” Catholics would flock back, forgetting that priests will use music that they at least think is the best for their parish. A switch of music to a more traditional style is just as likely to have people look elsewhere as abandoning all traditional Catholic music.
There are guidelines, but the principle of music selection is based on subsidiarity. I choose a lot of the music at my parish, and I have to do it based on my parish, not on what people around the world think.
