The ‘80s: a “lean period” for Dylan albums?

Thanks to Martin Cowan:

“Interesting to see the voting on this period of Dylan's releases.

“Not sure about "lean years" though (if you disregard weaker contractual obligation albums).

“Compare:
Street 78
Slow Train 79
Saved 80
Shot of Love 81
Infidels 83
Empire Burlesque 85
Oh Mercy 89

(all very strong albums, in my opinion), with:

TOOM 97
L and T 01
Modern Times 06
Together Through Life 09

“Which is the leaner?”
