first you need to update to version 0.885 or later. (I'll release 0.887 soon I hope)
run genXML for iTunes and then import this command (attached).
you then have to say "play song ...A... by ...B..."
you can't just say "play song A" or it won't work. You could keep the command "play song A" as well, but then you are talking about loading 11,000 songs twice. Also this command takes even more resources because it is a more complex command. We basically have to store in advance all the things you might say for each song. So a long song name, followed by a long artist name could result in about 100 or more different sentences that you could say just to ask for that one song.
