As you may recall, 1969 was the best year in the 1001 Albums You Must Hear, with 35 entries. The public likes 1969 too - with 41 entries.
So can we tell any more about the taste differences by comparing the lists for these two years?
There is a good degree of overlap - with 25 entries on both lists.
There were 16 entries on the Public list that didn't appear on the Critics list:
Caetano Veloso - Caetano Veloso
Catherine Ribeiro + 2 Bis - Catherine Ribeiro + 2 Bis
Creedence Clearwater Revival - Willy and the Poor Boys
Czesław Niemen - Enigmatic
Don Cherry - Eternal Rhythm
Fleetwood Mac - Then Play On
Gal Costa - Gal
Gal Costa - Gal Costa
Moondog - Moondog 
Pharoah Sanders - Karma
The Allman Brothers Band - The Allman Brothers Band
The Firesign Theatre - How Can You Be in Two Places at Once When You're Not Anywhere at All?
The Who - Tommy
Townes Van Zandt - Our Mother the Mountain
Townes Van Zandt - Townes Van Zandt
There is a few there with which I am totally unfamiliar. Looks like I'm not as well versed in the music of that era as I thought.
There are 10 entries on the Critics' lists that do not appear on the public list:
Captain Beefheart and His Magic Band - Trout Mask Replica
Chicago - Chicago Transit Authority
Creedence Clearwater Revival - Bayou Country
Leonard Cohen - Songs From A Room
Quicksilver Messenger Service - Happy Trails
The Bee Gees - Odessa
The MC5 - Kick Out The Jams
The Temptations - Cloud Nine
The Youngbloods - Elephant Mountain
The result is similar to the favourite artists analysis, and somewhat counter-intuitive. Where the two lists don't overlap the Public tastes seem to be more diverse and obscure than the Critics.
