@Steven:
The issue happens if you have multiple albums that will be one album later.
For example if a multi-disc album has been tagged with the disc name inside the album name by some douchbag:
"The Lamb Lies Down On Broadway - CD1"
"The Lamb Lies Down On Broadway - CD2"
When you now set the CD (X of 2) correctly and name all files "The Lamb Lies Down On Broadway" in their album tag, there will now be 3 albums listed in the album list:
"The Lamb Lies Down On Broadway - CD1"
"The Lamb Lies Down On Broadway - CD2"
"The Lamb Lies Down On Broadway"
Only when you switch to another view and back the two wrong albums will vanish.
EDIT: Is there any way to motivate you to do Nr 1, too?
I work a lot with Production Music and pretty much all my albums have multiple discs. The iTunes way ("X of X tracks" and "X of X discs") just saves so much space compared to having to show 4 columns. Or alternative another colum "discNumer - trackNumber of totalTracks", so "1-05/15" would also work.
