How about last played and play count stats, and smart playlists? Any hope at all for those of us who actually use some of the good things iTunes could do?
I am way too scared to try any of this right now, I don't want to spend days organizing stuff I already have organized.
And really the worst part about it all is the shaken confidence. Even if it "appears" to be doing ok for a bit, I'd be more worried about getting lulled into comfort only to, down the road, discover problems....perhaps at a time when you don't have an original Time Machine copy of it all
(make a complete non time machine backup asap everyone if you haven't)
