Group shown when only one item..

Simon, not sure if you consider this a bug or not but...

I'm using the Group tag which in most cases I have a MP3Tag script set to equal to the Composition tag. It generally works well in my browsing but there are a couple of quirks.

First off, where there is an album with only a single group, I would expect that the Group selection isn't shown: that is (as an example) where I browse
Tchaikovsky -- n Albums -- Swan Lake
the next level shown is a single selection "Swan Lake, Op.20" where as logically I would expect from there to show a list of tracks.

The second situation is the opposite really, where there is a number of Group tags in an album, but some of the groups only have a single entry: that is
Tchaikovsky"-- n Albums -- 1812 and other compositions
the next level shows amongst other things "1812 Overture, Op.49" even though there is only a single track and it would make more sense just to see the tracks.
