I go off topic from the thread title but we have a similar taste in music it seems, I like all your selections above. Another fabulous Fillmore East live recording was Neil Young and Crazy Horse from 1970, still sounds amazing.
Thread title IS a bit misleading as I was thinking of best POP song but basically best album of any genre. I'd also argue that Like a Rolling Stone is a POP song, it spent weeks, months even in the pop charts in the USA and here. There are plenty of fantastic singles of the 60's and early 70's...
Just one of each
Single - Like A Rolling Stone - Bob Dylan
Album - Dark Side Of The Moon - Pink Floyd
