I think you just became the first recipient of @steemitboard's still unreleased Steem's Understatement of the Week badge. ;)
To be honest, I think that Björk may be one of the most challenging artists in this aspect. That not in the least because she has continuously improved, both in telling a narrative and in her experimental sound, risk factor.
Where other great artists like Bowie and Zappa have often dropped turds because they may have become too experimental at times, Björk is also a perfectionist (and hated for it by many who didn't live up to her standards). Add to that her innovative element and I can not say that there's much Björk work I can not make time for to listen to in a focused way.
That said, maybe I should disclose that with close to 225k scrobbles on last.fm, Björk is my 5th most listened to artist. I may be biased.
Out of pure curiosity, I just checked the Spotify thumbs up ratings for her studio albums and go figure that Biophilia, which is possibly her best album composition, is among the lowest rated albums on average (I looked at track ratings). Post and Homogenic being among her highest rated albums, the latter despite many less plays than the former. Yet musically, they probably (definitely?) aren't up to par with Bowie's earlier releases. Utopia and Black Star would line up nicely in "best album" level tho. But that was an outlier for Bowie, while Björk has been much more constant than he was, even as early as in his second decade.
That woman is a perfect enigma. I wonder if she herself actually gets herself. Or knows how bloody darn excellent she is.
On my last.fm she's top, but only just ahead of Eels.
