The collection browser prepends the track artist name to tracks shown under various artists/compilations. This behaviour is useful, because usually the tracks on compilations have different track artists. (Other people think exactly the opposite, see bug https://bugs.kde.org/show_bug.cgi?id=276039)

If there is an album where the tracks have different artists but all tracks have a unique album artist different to "Various Artists", the album is shown under the album artists name. This is also useful. But unfortunately the track artist is not prepended to the track title in the collection tree. I would like to have also here the track artist prepended to the track title.

A common usecase are tribute albums: They are tagged with the same album artist and different track artists. The album is shown under the album artist in the collection tree, but one cannot see the artists of the single tracks.

In the bug https://bugs.kde.org/show_bug.cgi?id=252790 a patch was introduced for the current behavior to prepend the track artist to the track title under Various artists. I think something like this could do the job:

src/browsers/CollectionTreeItemModelBase.cpp, line 195:
QVariant
CollectionTreeItemModelBase::dataForItem(...)
{
.
.
-  if( album && artist && album->isCompilation() )
+  if( album && artist && ( album->isCompilation() || (album->albumArtist() != track->artist)
                    name.prepend( QString("%1 - ").arg(artist->prettyName()) );
. 
.
.

Reproducible: Always

Steps to Reproduce:
Create some tracks with the same album title, the same album artist (but not Various Artists) and different track titles.

Actual Results:  
The album is shown under the album artist in the collection tree. The second layer shows the album title. The third layer shows only the track title.

Expected Results:  
In the third layer the track artist should be prepended to the track title.
