A lot of my covers don't show up. I think it's the ones I downloaded through iTunes automatically.
You could consider adding a feature I think iTunes has been missing for years, a "cue up" button that will set a song to play after the current one is over.
When there's nothing playing, I feel like the blank album cover is pointless.
EDIT*
When the albums for an artist show up in the sidebar, clicking on once should expand it, not just highlight it. I'd rather not click on the arrow if it's already taking up all that screen space, because highlighting it doesn't really do anything.
