The auto lookup worked on a per album basis. In the settings, I do have local artwork checked. Should I specify my root music folder there as well? There is no artwork in the root. It is all in the artist and album folders. I also flushed the cache and then pre-cached the artwork which seems to have helped.

So now it's fixed ? In that case probably some old leftover stuff in your cache. There have been a lot of improvements to the music artwork last couple of months
