I need someone's help with sorting, cause I just can't figure it out.

I use Single Column Playlist, sort by group like this: $if($stricmp(%comment%,'single'),!noheader!,%album artist%)
And my default sorting string is:
$if($stricmp(%comment%,'single'),%album%,)|%album artist%|$if(%tracknumber%,%date%,)|%album%|%discnumber%|%tracknumber%|%path_sort%

So, some tracks have 'single' written in the comment field, cause I don't have the rest of the album, or they are rarities.. whatever. Some of them have the %album% field, some not. They display with no header and with a different color in the single column playlist.

Now what I get is this:

-single track (with no %album% field)
-single track (with no %album% field)
----------------------
%artist% header
----------------------

-album track 1
-album track 2
-...etc

-single track (with %album% field)
-single track (with %album% field)

And What I want is to display all single tracks at the end of the %album artist% group, like this:

----------------------
%artist% header
----------------------

-album track 1
-album track 2
-...etc

-single track (with no %album% field)
-single track (with no %album% field)
-single track (with %album% field)
-single track (with %album% field)

I have noticed that if I change the first part of the string "$if($stricmp(%comment%,'single'),%album%,)|" to:"$if($stricmp(%comment%,'single'),%title%,)|"
the single tracks appear at the end, which is fine If the playlist only shows one artist, but not for the whole library, because the are all together at the end

For the single tracks, I don't care much about the sorting, as long as they are placed at the end of the artist group.

wow. long post. I'm hoping I have made myself clear, excuse my english...If anyone knows how to do it, please help out, cause I have tried lots of things and I cant get it right

thanks in advance
