music fanart during play back

I’m not really sure if this is a skin issue or a Krypton issue but I can’t get artist fanart to show during music playback.
I’m not using the fanart slideshow addon. I’m just using the default fanart setting.
My files are set up as follows
Artist
extrafanart
album 1
album 2
album 3

When I select FANART in the playback settings the background just stays blank. Is there something else I need to do or are my files not organized correctly?

Thanks in advance.
