Haha, I've read all of these except for Candide and whatever Jitterbug is. So pop me down for Candide? You're awesome. EDIT: we're still doing the thing where we pass them along to people, right? I am excited.
Maybe it was of a time and age. I also loved Robbins' Still Life with Woodpecker but picked it up again 10 years or more after I first read it and was completely bored. People have insisted I read Even Cowgirls Get the Blues, saying that I'd love it - but I didn't get very far. Same thing with Housekeeping by Marilynne Robinson, even though I tried and tried. Books have their moment in an individual life and it's hard to know when exactly that moment comes.
Books, like music, certainly have their moment. I loved both Still Life with Woodpecker and Even Cowgirls Get the Blues, but I read them around the same time in life. They were recommended to me by a girl I was smitten with, that probably helped my enjoyment.
