Just wondering if there is anyway to add catergories to WMP9? For instance...

There are 3 main catergories under "all music" - Artist,Album & Genre..I want to add "Single" to this list..

Just to tidy things up basically, so that if I tag certain tracks then they will apear under "single" and not "album" Or even a sub-catergory "single" under "album" would do...

Is that confusing??? So that it looks like this...

-All Music
+Artist
+Album
+Genre
-Single
Single1
Single2
Single3

etc..etc..
