Additional weirdness when using custom 512x512 NoThumbAudio.png:
1) Introduce new custom NoThumbAudio.png and run Spotlight on Album1. The new missing thumbnail image appears. Good.
2) Introduce a different custom NoThumbAudio.png and run Spotlight on Album1. The previous custom missing thumbnail image from 1) appears, not the new image as one would expect. Very bad.
3) Now run Spotlight on Album2 (by a different artist). The new missing thumbnail image is that from 2). Good.
4) Now reuse new custom image from 1). Run Spotlight. Album2 retains it custom missing thumbnail image from 2). Very bad.
etc etc
A given album seems to remember the first custom missing image thumbnail and uses it forever more, even after a different custom missing image thumbnail is introduced.
Yes, I stopped all MC processes, even rebooted, and this "remembering" situation still holds.
What the heck is going on here?
