Add Mood/Label to the Song List filter options

Feature description:

I would like to request adding two more fields to the Song List filter options: Mood and Record Label.

Problem solved:

Ability to filter songs by mood or label, given that the Mood List view and the Label List view only display albums and you can only browse one at a time.

Brought benefits:

Have more options to navigate the song list using smart filters.
