It really confuses me when people don't get subjectivity. Statements like "Song x is bad" or "Band Y is the best in the world" really mean "I don't like it" and "I like them".
Last night we rehearsed. It started off pretty rocky, ragged and out of time, mistakes-a-plenty. 3/4 of the way we settled down and things got better. At least that's what I thought. The first time I felt "Yah, we nailed that one." I looked around and saw my band mates shaking their heads in obvious disgust.
If the people who created the tune can't agree if it's shite, what's the point in making value judgments?
