Something like this...

on substitute()
tell application "Spotify"
set _title to name of current track
set _artist to artist of current track
set _url to spotify url of current track
end tell
set message to _title & " - " & _artist & " " & _url
return message
end substitute

substitute()

Thanks, didn't know it was just a plain text file.

Would it be possible to take away the "/me " and provide a clean "Artist - Track" format? That way we can use it to update status.
