I had version 3.2.1 installed, reinstalled to version 3.2.4 Beta. Now on Blues genre fan art is displayed together (Rock, Blues, and so on) Is this the plan?

I've apparently not been making myself clear.  Artist Slideshow knows absolutely NOTHING about genre art.  It shows art attached to an artist or a fallback slideshow, that's it.  Whatever you are seeing is because the when the artist is playing there are images in the artist folder that either you put there or were downloaded.

Thanks for the answer.
So, while displaying genre fanart in the absence of an image of the artist has not yet been implemented? :-(
It seemed to me that in version 3.2.1 genre fan art was displayed

Genre art is not now nor has it ever been supported in AS.  The only thing I can figure is that at some point you had a skin that did genre art in the background.
