How do I copy the name of the song currently playing on an internet radio station in iTunes?
Use this AppleScript to copy the current stream title to the clipboard:

tell application "iTunes"
    set stream_title to (get current stream title)
end tell

set the clipboard to stream_title
display dialog stream_title &amp; " copied to clipboard." -- delete line to omit dialog


To install it as iTunes script, copy &amp; paste the above into the AppleScript Editor and save it under Library/iTunes/Scripts in your home folder, giving it a sensible name, such as Copy Stream Title to Clipboard. Create the Scripts folder if it doesn't exist. This will make iTunes grow a little script icon in it's menu bar where you can select the script.
