i'm also really into volta at the moment, much more so than medulla (which is finally growing on me). i like the tracks with anthony whats-his-name. i too consider it her third best after homogenic and post.
as for favourite bjork tracks, its gotta be hyper-ballad, and the album version (which is the howie b mix i think) of all is full of love.
and yeah, markus the comment 'bjork tends to attract some strange people', i mean i don't think i'm too weird but i was chatting to someone recently and mentioned i like bjork, and she thought i was weird just for liking her. then again, she was a big george michael fan
