Comment 12 for bug 135618

here is a patch that implements a new way of sorting collections, called "Album Artist" - sorts by album artists where present and artists where missing.

this also fixes the bug where album artists would jump into "Artist" mode, so you get for example "DJ Koogi" in "0-9", because a track from his compilation is by "2 Cities"
and also a related bug, where this specific entry is supposed to contain one track but instead contains the whole album

it simply makes the Collection feature better overall :)
