Music library no longer supports well Personal MP3 files playing when not in an album

IOS 18.5

Strange regression observed.

Unless a personal MP3 song is declared part of an album, it is not visible in the "composer" view of the iPhone library.

And if you declare it part of an album, in does not show the MP3 image of the file while playing, it shows a dummy for the (non-existent) album.

I have not found an easy way to circumvent this brand new fulty behavior.
