re: Which genre of music you can’t stand?

Can't stand speed/thrash metal although I like a lot of what I'd call classic heavy metal.

Rap mostly sucks, although I can handle some 90's rap--a bit more jazzy backgrounds, less gangsta lyrics.

As far as Jazz, someone said "Jazz. They’re just making that shite up as they go and it sounds awful.". There's a great scene from "The Office" where Angela is distraught and crying and she says, "...and Jazz--why can't they just play the right notes?"

Ironically, jazz musicians are generally the most highly trained (outside of classical). While I always enjoyed New Orleans jazz, I never got into more "trad jazz" or "modern jazz" until my son went to NOCCA for jazz. Now I appreciate it much more, although it does get annoying when some dude takes off for 20 minutes on a maniacal clarinet solo.
