this is an examination to the bottom! How deep can you go?
Your explanation is clear, but I have to admit that for me it begins to be a little adacadabra.
I'll wait for your results, There are not much doctor/expert in the field.
Thanks for your deep analyses, and sorry for my mistyping and horrible school English.

There isn't anything that can be done in moOde because many of the files are not valid FLAC files and thus cannot be read by the cover art parser.
The list below was generated by using the Linux command "file" which analyzed the files from the test set that you provided and printed out their format.
Files marked as "FLAC audio bitstream data..." are valid FLAC files. Files marked as "Audio file with ID3 version 2.3.0..." are not valid FLAC files. As @TheOldPresbyope pointed out, the invalid FLAC files have the marker string "ID3 " in the first 4 bytes of the file header. A valid FLAC file would have the string "flaC" in that location.
I also took a look at the metadata blocks in the invalid FLAC files and there was no PICTURE block, thus no embedded flac cover for moOde's cover art parser to extract, even if it could parse the invalid format.
I don't really know how to fix or convert these files.
