@mustbethemusic - out of curiosity, do you think something can be 'good', even if you don't happen to like it? You primarily enjoy jazz - great!
I don't like jazz at all, but I wouldn't question its worth because of that - people have different tastes, and I would never say that one person's taste is 'better' than another's...
I'd say the same about blues, country, and lots of other genres I don't like, besides rock, pop, hip-hop, and reggae, which I do like... I'm not required to like it for it to be good, but maybe that's just me.
