Hot Dayyam! I know some people are pissed about the crippling of share-anywhere streaming, but Apple fixed a major (well, major to me) bug in this release: although the What's New/Readme doesn't mention it, this update now allows Applescript to get correct Track/Artist/Album information from a Shared track. Which greatly expands the utility of my Ant Tracks client.
(And, yes, I updated, instead of stubbornly holding onto version to 4.0 to keep the ability to stream anywhere. The only people I've been sharing with are on my subnet at work anyway, and half of them upgraded. Since 4.0 and 4.0.1 don't interoperate, it was a matter of following them or losing out on Sharing altogether.)
