I like the window

This is hard to read
ListItem(ListItem([Artist],0),0,/,)If(ListItem(ListItem([Artist],1),0,/,),//ListItem(ListItem([Artist],1),0,/,),)If(ListItem(ListItem([Artist],2),0,/,),//ListItem(ListItem([Artist],2),0,/,),)

This is so much better
ListItem(ListItem([Artist],0),0,/,)
If(ListItem(ListItem([Artist],1),0,/,),//ListItem(ListItem([Artist],1),0,/,),)
If(ListItem(ListItem([Artist],2),0,/,),//ListItem(ListItem([Artist],2),0,/,),)

Unfortunately the single line differs from the multiline in formatting

Argerich/Kremer/Maisky (Single line)
Argerich /Kremer /Maisky (Multipline)

It look like the CR is included in the output in case of multi line expressions
Please remove this from the output

If we ignored the CR, there wouldn't be any way to output a CR.  That seems bad.

Matt,
What you are advocating here is that formatting an expression also yields a different output.
Please reconsider

You can split to a new line after a comma.
 
However, I'm wondering what your expression there does. It seems like there is probably a more efficient way to write that.

In the Artist field I have multiple artist all written as Last Name, First Name
The expression concatenates the last names.

Matt does have a point, in a multi line field like thumbnail text it is very convenient if the formatting of the expression (CR) is honored
If we take this to the limit, in a single line field only the first item should be displayed :)

What I propose is that in case of a single line field the CR is ignored completely.
