Ok, thanks for the explanation and understand the extra work involved.  

No worries.  It kind of comes with the territory when you maintain an addon.  Not, you know, the amount of work it takes to maintain Kodi, but still...    The good news is you finally guilted me into looking at it again, and I have some test code that isn't crashing (for me at least) on github (in the next-version branch) that uses the new Kodi music artwork location. I haven't written the conversion routine yet, but it's a start.
