OK, fine. This is tiresome and you're probably just trolling, but I'll play for the time being.
Is there such a thing? I mean, a survey or something where critics and musicians form some official consensus? Also, is there a problem with less-tenured music historians - why are only "long-time" historians included?
You
are trolling, aren't you? Why am I even responding? I have literally never heard a single historian, writer, or musician who's not a Sunday morning Breakfast with The Beatles radio show host voice this, much less enough to say it's some sort of settled issue or whatever your appeal to authority is. Also, "may have" is not a declarative with any value.
Who has ever said this? For a guy who sang lead vocals on about half the songs his band pumped out? A man who famously didn't like the sound of his own voice and tried to alter it electronically and stylistically throughout his career? He's generally regarded more highly as a lead singer than Freddie Mercury? Robert Plante? Axl Rose? Janis Joplin? Roger Daltrey? Mick Jagger?
As noted above, this does not equal "great" or anything close to it.
By whom? He wrote some good songs and was for a long time overshadowed and underrated as a writer. But to suggest he's one of the best and that this is generally accepted conventional wisdom is embarrassing overcompensation. A man who wrote no more than 3 songs widely regarded as "great" is one of pop music's best songwriters? I mean, where do you go after that top trio? "Taxman?" "My Sweet Love?" C'mon.
This sure sounds like a personal opinion. You promised there were no personal opinions here.
Could you point me to the general consensus among critics and musicians that this was truly insane?
Interested in this - could you provide some examples? I've already covered why the rest of your "intangibles" argument is not particularly compelling.
Beethoven? Pshaw! Mozart? Pretender. Armstrong? That guy's a hack. Hendrix? Pffft. This sort of rigid, unnuanced hypercertainty about matters aesthetic just totally derails discussions about what is ultimately a subjective topic.
