I noticed that when I select an artist with songs which has no album definied I can’t get to the songs.
I too have run into this problem. Perhaps if the album tag is not found the tracks can me moved to an “(unknown)” entry in the album column?
To avoid potential slowdowns caused my a multitude of tracks from various artists with no album tags trying to load all at once, would it be reasonable to only have the “(unknown)” show in the albums column once an artist has been selected? In other words, maybe the “(unknown)” entry shouldn’t show up by default, only after an artist selection has been made… if that makes sense.
