The methods that worked in 10.4 - 10.6 don't seem to work under Lion anymore, namely:
defaults write com.apple.iChat iTunesMessageFormat -string '♫ %Track - %Artist'
defaults write com.apple.iChatAgent iTunesMessageFormat -string '♫ %Track - %Artist'
I've also verified that the com.apple.iChatAgent.plist has the iTunesMessageFormat entry.. no dice, only shows as Title - Artist.
Does anyone have a method to set 10.7's iChat 'Current iTunes Song' status back to Artist - Track order?
