Well I have had champagnes from cheap La Scala Spumante (CDN$5) to Cristal, various Dom Perignons, and extremely expensive $500 - $1000 stuff.
For me, since I exclusively care for sweet dessert wines, La Scala Spumante tastes fantastic. Most high end stuff is just too dry to even finish.
I am aware of this disability and its implications. I blame beer shandies from my childhood during long trips to the beach for vacations.
Also for taste there is actual genetic differences in taste buds: scientifically not everyone can taste the disgusting chemical that makes brussel sprouts taste like crap scraped off the pavement and distilled for example.
On to music. Some stuff sounded better on my old intro stereo from my youth and completely unlistenable on my good system. This would be the stuff engineered to sound good only on cheap club systems. However, you can spend some time with it and erase your memory of it, replacing it with cleaner sound on a good system.
Additionally taste and sound are subjective AND influencable. If you give someone something to taste and tell them there is grape or orange in it they will likely suddenly detect that. Same with music. You could even have some hot chick/dude tell someone they like some music or sound and they will be hard pressed not to have an improved response to it.
Time also influences memories of music. Stuff you heard a lot when young but hated can suddenly be nostalgic and cool 10 or 20 years later. Your brain recalls hearing it and not the hating it part.
So bottom line, I want trained golden ears in charge of rating my music system. I simply do not trust people who in blind taste tests can not tell the difference between cat food and pate (although I think that says more about pate than taste buds).
