ah, see... that's why it's good to have beta testers!
If you look in your artist.xml on line 13040 you'll see this: <Title></Title>
Obviously I need to modify my code to account for this, but in the mean time you just need to edit that line (actually you have a few so you better search for <Title></Title>). And if you want to do regular updates of the xml from MediaMonkey obviously you'll have to fine the song with no name... Not to be confused with song horse with no name on line 18778 who never caused any problems...
My next release will check for this of course if possible. Actually it might be necessary to modify the mediamonkey script that exports the xml.
Yes. I've attached an updated script for mediamonkey. I can see that I was checking for blank names on artist and album but forgot to make the check for songs...
