OP,
Good thoughts.
But in reality, music moves on and appeals to the next generation. Bach was new music once. The truly great stereo recordings were in the late 1950’s and very early 60’s. I have a couple thousand vinyl albums collected since the 60’s. Many audiophile pressings from the late 50’s.
My digital and analog ends now sound the same (see my UserID)… so, while some recordings are good, ok, am\nd great… I think some music stands the test of time and some doesn’t. Bach, Beethoven, Mahler, Billie Holiday Miles Davis, The Beatles, The Who, Crosby, Nash, and Young, Passport, Afro-Celt Sound System…. Etc will. Many will not. My niece loves XXX… I agree, great. There are bands that bond to a culture and time and will emotionally capture the time… some will remain timeless.
The fidelity of the recording are secondary.
