I have had this annoyance with Leopard. When I display the "Currently Playing" track from iTunes in my iChat status message it displays the string in reverse order. It looks like "Exploder - Audioslave", when I think it should look like "Audioslave - Exploder". I also miss what an old AppleScript used to do back on 10.4 (Tiger). It would display a very useful musical note prepended to the "Currently Playing" string. To fix all of this in Leopard launch Terminal,
Applications->Utilities->Terminal, then execute each of the following commands.
defaults write com.apple.iChatAgent iTunesMessageFormat -string '♫ %Artist - %Track'
Note: I found that I had to quit and restart iChat to display the string properly.
