But "undefinable" doesn't mean the term is of no value, or anyway that it didn't have value in its heyday. Which is to say that just because I'm generally thinking we'd have been better off without it (and so I'm assuming that people would have found different and maybe better ways to say what they were saying), doesn't mean they weren't saying something interesting, and wouldn't have yet more interesting things to say if they followed up on what they were saying.

(Note below that I just said to Mordy: "And then the next point would be, can't someone present such an argument not because he's a rockist but because the argument is right in that particular circumstance?" That is, I wouldn't be committed to the idea that X necessarily declines into non-X, but I think (or thought) in this particular instance that punk had declined into fake punk.)
