I need to be reminded, ever so often, that not everyone knows the details of the entire catalogues of Dylan, Springsteen, Simon and the like (AllMusic is still not a ubiquituous name!); not even people with an interest in music of that time. In fact, even ignoring specific artists, not everyone thinks about music in terms of albums. I observe this not as something to be proud (or ashamed) of, but as evidence that my aim of in-depth knowledge (in popular song, but in other areas too) is not as common as I sometimes think.
