Acctually I had noticed that, though also the track 'Cocoon' which is about love, and (imo her best ever song) 'Pagan Poetry'.
It is very possibal that there is a influence, as Björk is a reguler at the Royal Court, and in this months 'Wire' magazine talks about how she likes story tellers, including Beckett.
Acctually the whole album is just mindblowingly good, imo 'A Echo, a stain' in one of the weaker tracks!
