For audio only, I have customized thumbnail text to show separate displays for classical and non-classical works. For classical, composer is used first, with artist second, whereas for non-classical artist is used and composer is not. I also have a custom field for source/format, such as CD, Vinyl, HiRez, MP3, DVD-Audio, Internet Radio. That is displayed if it is not CD. It also uses different font sizes, colors and bolding. Since classical and non-classical use a different number of lines, what the last two lines show depends on the genre. The code works for both mixed genre views and single genre views.
EDIT: Interact swallowed my bold and italics commands, so here is the code for real
<b>[Genre]<//b>
If(IsEqual([Genre],Classical,8),<b><font color="0000FF">[Composer]<//font><//b>,<b><font size="115%"><font color="0000FF">[Artist]<//b><//font><//font>)
<b>[Album]<//b>
If(IsEqual([Genre],Classical,8),[Artist],if(!Isequal([Media Sub Type Audio],CD,8), <i><font color="0000FF">[Media Sub Type Audio]<//font><//i>, ))
If(IsEqual([Genre],Classical,8),if(!Isequal([Media Sub Type Audio],CD,8),<i><font color="0000FF">[Media Sub Type Audio]<//font><//i>,), )
Here is the code
>[Genre]<//b>
If(IsEqual([Genre],Classical,8),<font color="0000FF">[Composer]<//font><//b>,<font size="115%"><font color="0000FF">[Artist]<///b><//font><//font>)
>[Album]<//b>
If(IsEqual([Genre],Classical,8),[Artist],if(!Isequal([Media Sub Type Audio],CD,8), <font color="0000FF">[Media Sub Type Audio]<//font><//i>, ))
If(IsEqual([Genre],Classical,8),if(!Isequal([Media Sub Type Audio],CD,8),<font color="0000FF">[Media Sub Type Audio]<//font><//i>,), )
Here is an example. It is smaller than I normally use to show the various genres. Hence the lines are more wrapped than normal.
