A very thought provoking OP. Lots of great albums mentioned in this thread, but few IMO have 100% great tracks. I think the artist that gets closest most often for me is Bowie ... and I think Aladdin Sane is closest to perfection. I would have to listen again to Marianne Faithfull's Broken English but I think this gets close too. For me not a single Beatles, Cohen, Dylan, Beach Boys, Abba, Mitchell (plus many others) ... achieves perfection, but many are truly great.
Thanks to the OP for starting a very interesting thread.
