Taste is completely subjective. Your taste is only really "good" or "bad" compared to what your taste could be, not compared to anyone elses.

I do think it's possible for people's taste to come from a place of ignorace (ie. not having a great amount of knowledge about, or appreciation of, music), and I do think that leads to one being more close-minded about music, which leads to only liking certain styles or genres or specific music artists. I think, for my money, I don't really trust musical opinions that come from a place of ignorace. So if you're like "Oh, I like music, just not country, or hip hop, or jazz, or industrial"...or whatever genres you just write off because you've never actually developed an appreciation for it, I'm going to think your taste in music is tainted by those prejudices, and have less respect for your opinions as a whole.

It doesn't mean your opinions or tastes are wrong or "bad", it's just they are less refined I guess. I think it is possible to have a more or less refined palate when it comes to music, just like anything else.

It's like, I'm not a wine conniseur, but if I were one, I would like to have a well rounded palate that can appreciate and understand the various types of wine from all over the world. That's kind of how I feel about music and that is the type of musical palate I try to maintain.

I don't mean for this to sound condescending. Everyone has their thing that they are really into and know a LOT about, and I just think for some people that thing is music, and for some people it's not. It's my only thing like that. I could speak for hours on just discussing the difference in the Stones from '68 - '72 or the production in early '90s through mid '90s hip hop...or I feel like I could write a masters thesis on what changed between Radiohead's The Bends and OK Computer (I prefer the Bends btw).
