Details

Based on the comment patch from Nicolas Pennequin (see http://www.rockbox.org/tracker/task/2974) I created a patch to enable usage of the albumartist tag and the comment tag for both displaying in the WPS as well as using as filter and conditional in tagnavi.config.

If you set the albumartist tag e.g. to Various for all tracks of compilations and to the track artist for all tracks of non compilation albums you can easily create a "browse by albumartist" menu item in tagnavi.conf which shows only artists who have their own album (which usually reduces the length of the artist list a lot).

Example: "Album artist" -> albumartist ? albumartist != "Various" -> album -> title

You can also create a Compilation menu item with: "Compilations" -> album ? albumartist == "Various" -> title

For mp3 files you have to set the BAND tag (TP2/TPE2) which is commonly used for album artist.

Since for ogg vorbis and flac files no single standard tag exist, the patch reads the tags ALBUMARTIST, ALBUM ARTIST (with one space inbetween) and ENSEMBLE which are the most commonly used tags for album artist. Each of these tags will be recognized by the patch.

In tagnavi.config you have to use albumartist or ensemble as filter or in conditionals. album artist (with space) is not possible since spaces are used as delimiter between tags. Both of albumartist and ensemble will work in tagnavi.config, it doesn't matter whether you tag your ogg/flac files with an ALBUMARTIST, ALBUM ARTIST or ENSEMBLE tag.

In WPS the album artist can be displayed with %iA

The comment tag can e.g. be used for titles of classical pieces (like "Symphony Nr. 9") if more than one piece are on an album. In tagnavi.config simply use comment as filter or in a conditional. In WPS use %iC to display the comment. Of course you can use the comment tag to store whatever you want.
This task depends upon

New version which displays album artist and comment also on the id3 info page (including English and German labels). I also added support for the mp3 COM tag (id3v2.2) in addition to the mp3 COMM tag (id3v2.3) but I cannot test it since I have not tagging program which writes v2.2.

I forgot to mention. The basis for this patch was not the patch from Nicolas Pennequin but the comment patch from Robert Kukla (roolku) (see http://www.rockbox.org/tracker/task/6301). I don't see a way to modify my original task (I think this must be possible somehow), so I want to clarify that here.
