Downloading it at the moment. A bit scared of the tablet-style interface, I like lists in iTunes. Navigating through album covers is not efficient
EDIT : using it for the first minutes... I don't like it either but maybe I'll get used to it... I really liked the way iTunes 10 put songs who are in the same album together under "artist" even using the column navigation, I used it an hybrid way (column navigator on top for fast search, and the bottom of the screen for the normal view where the albums and songs were grouped by album with the cover) and I don't think it can be configured for that. Cause now, when you are under artist, you have to scroll down so far to find the artist you wanna find, because you can't do a first filter by selecting "swedish metal" for example and have only a few ones left.
EDIT 2 : actually, it's all down to using the "gender" tab instead. So it's like Gender is a master tab for Artist, which is a master tab for Album, which is a master tab for Songs. I think i'll get used to it
EDIT 3 : the search function is very nice
