Internally Deformed
Farseer of the Paranormal Abysm
Offer evidence that you're correct and I'll agree with you. The absence of evidence to support the absolute quality that you claim exists can be seen as evidence that music is subjective.
The absence of evidence isn't evidence of absence. I already posted this to help you out with that concept, but perhaps you'd better read it again:
A case less clear might be if you and I had differing eyewitness descriptions of the criminal in a robbery we both witnessed. You might say that as the criminal is not on hand to settle the debate, our opinions are entirely subjective. But somewhere the criminal does exist, and he has a definite appearance which either confirms more closely to my account or to yours.
If what you say is correct, then it would certainly be valid to comment on the transitions in their music if you don't like it but I still don't see how that would objectively undermine the quality of their music.
It's one objective measure by which you could assess the music. The albums are still cool because they do well on so many other measures, but they're less good than the later albums which (as well as being good on a riff by riff level) are also more cohesively written.
