So I started trying to use Emby's Collections feature.
Emby's WebApp interface allows building collections containing movies, entire tv series, a season of a tv series, episodes, artists and music albums, tracks...
It seems any media item can be included on a collection if you press the "more" menu.
Resulting collections can, thus, contain various kinds of media items.
When navigating throughout the interface, though, only movie libraries will present "Collections" as submenu.
Should I stick to movies on a collection? Is it ok to create music album collections?
Is there a reason why there is no "Collections" item on music library submenus?
