Yes, the panes allow multiple selection but that only permits to OR the
criteria.

Here is my idea of a GUI for quickly selecting things from a database -
a group-sort widget. This is a tree widget with reorderable columns, all
db entries are grouped according to the first criteria, then the
second... When there is only one match, it is displayed as a single
line. Example screenshot:

Album|Artist|Song|Last played||Add column
Les inrockuptibles, une rentrée 2002
	Kelis - Milkshake - Yesterday
	Matthieu Boggaerts - Dom - Today
	I am Kloot - From your favourite sky - Last month
	...
Karma
	Delerium
		Silence - Yesterday
		Koran - Today
		...
	Sarah McLachlan - Silence - Yesterday
Tasty - Kelis
	Milkshake - Yesterday
	...

Songs can appear at different places when they are from many artists.
If I am playing from the inrockuptibles, I can select milkshake, move
the artist column left, and end up browsing Kelis like this:
Artist|Album|Song||Add column
Kelis - Tasty
	Milkshake
	Sugar honey iced tea
	...


Finally, here is how it addresses the original question. To select
tracks both by enigma and by deep forest, you can add another artist
column:
Artist|Artist|Song||Add column
Enigma
	Enigma
		...
	Deep forest
		Hiyahiyahey
		...

I think this is both a powerful and simple interface. The backend can be
a generic database, so maybe the widget could be part of libgnomedb.
I'd like some ideas on how to implement this - I admit writing a gobject
is a bit daunting to me. I don't know yet if one should just write a
tree model, or inherit from the tree view as well.
