What is wrong with covers?

[Lapsiuta]

For example in folder "0 - DANCE":

- there is no file folder.jpg, folder.png, cover.jpg or cover.png

- there is no audio file with an embedded cover

no any file at all

0 -DANCE\ - no covers or files, just subfolders
0 -DANCE\Dr Alban\- no covers or files, just subfolders
0 -DANCE\Dr Alban\Album_name - cover JPG
0 -DANCE\Dr Alban\Album_name2 - cover JPG

0 -DANCE\ displays Radom cover from albums subfolders.
