In all honesty, I think that Björk is an overrated singer. While I would agree that she has a unique voice and that her lyrics are creative, I don't believe that uniqueness and creativity always suffice. That said, I don't think that there's any questions that her videos are the best around.
As an extra bonus, I decided to throw in The Brunching Shuttlecock's Björk Song.
"Björk, Björk, were you brought by the stork..."
