COMPOSER tagging and viewing

[simbun]

Assuming that part of the question is about how to only show 'HD' in the album name and not all the other values from the tags (be it Comment or #AudioQuality ) e.g. Dark Side of the Moon CD

The only way I know to achieve this kind of functionality would be via tagUpdate.
What you'd need to do is to create a new tag based on the value of HD in the Comment/#AudioQuality tag, something like:

Code:

@COMMENT=HD
+HDCONTENT=HD

Then apply your album tagFormat
Album.displayFormat={$album^$HDCONTENT^ ^}
