No artwork preview in Finder browsing audio files
While browsing audio files in the Finder (MacOS 10.14.6), audio file previews appear as generic music icons (with play button in some cases). This is true in column view with preview column, icon view, and the new gallery view. Also, no album art shown in Quick Look.
Incredibly this remains a problem without any resolution that I'm aware of.

Of course, in Finder view options for each mode, "show icon preview" is selected. All other media, including images and movies, show previews as expected. Incidentally the same exact thing happens in Path Finder 9.
I've tried pretty much all the recommended solutions. iTunes 12 in Mojave no longer has Voice Memos to delete. I've deleted ~/Preferences/com.apple.finder.plist and relaunched Finder and rebooted, etc.
Can anyone still on Mojave see if this is the case with them as well please?
Any solution?
PS: my music, and the iTunes LIbrary, is on external drives. iTunes 12.9.5.5. MacOS 10.14.6.
