Sometimes there's two or more CDDB playlists for a given album.
Some such playlists seem nearly identical, (as when the 2nd
list contains a spelling correction), in which case the user has to do
some eyeballing to find the difference.  (Last time I had 2 lists
and I couldn't find any difference -- so after wasting a minute I
picked one at random.)

In such cases, it might be better if 'abcde' could run a 'diff' util on
the lists.  Preferably a 'diff' util that's able to highlight individual
characters.

Hope this helps...
