You may not understand this, but most other people go out to nature to enjoy nature. Blasting music kills the experience.

I'm guessing both of you are just kids whose parents missed this particular lesson.

I also go out to nature to enjoy nature. I also enjoy silence outside. You mind hikers with music and I don't.

You may not understand this, but there's such a thing as disagreement and preference.

I absolutely understand differing preferences.

The difference is that someone blasting music is IMPOSING their preference on everyone else.
