Subjectivity : "Judgment based on individual personal impressions and
feelings and opinions rather than external facts".
So there we go, subjectivity is about opinion. Guess what... taste are about opinion too!
Taste : "Ability to notice, appreciate, and judge what is beautiful, appropriate, or harmonious, or what is excellent in art, music, decoration, clothing, etc."
Which may differ from a individual to another, because of the subjectivity of the criterias.
Stop trying to lower what I'm saying, I'm just basing myself on fucking facts. Taste is not something you can judge of. You really like asparagus but everyone keep telling you it tastes like pure shit... still you find the asparagus very good. People will tell you that it cannot be good because there is some kind of substance in it that makes it untasteful, but you'll like it anyway. THAT is taste and this idea can be applied to anything, including music. If you like untalented bands, nobody can say you have bad taste, that's what you like.
