There are mistakes in this post.
Firstly, there is some music I like that I accept isn't very good, but there is no accounting for taste.
Secondly, as with all genres, there is good jazz and bad.
All the jazz that I love is unquestionably good and I can easily identify several different types.
You may not like it and that is fine, but you may not dismiss it as 'crap'.
Finally your numbers are wrong - you divide your third type into two, making a total of four.

he also dismisses all hip hop as rubbish.
Wonder if he's heard The Roots?

And if he's a big instruments snob how can he not like Giant Steps? As a piece of music it's incredible.

Diff'rent strokes for different folks, doze.
Some people just don't like jazz.
Hip hop can be difficult to relate to for some people, including me.

True.

Stop being so reasonable.

plus, just as with any other art, there is music worse than other music.
Liking it doesn't make it good.

He also forgot to include the genre of "Music you listen to while raping a 14 year old in the the hope that they will ultimately kill themselves"
