Vespertine is one of my all-time favorites too! Post and Debut kinda tie as a close second, and Biophilia third. Haven't heard her new album, but I liked Vulnicura quite a bit. I agree that Volta was one of the worst for me, although I did like Declare Independence and a few other tracks. I just could not with Medulla though. x.x Maybe it's due for a re-listen?
