Lately I've been using one piece of music as default background music, though, so if it's not otherwise indicated, that's what it was. The default should be listed up top.

I try and use curly braces ("{" and "}") to group together pieces that were played simultaneously, but given the wide variety of ways things can be mixed together, it's not always easy to write it down precisely.

"Coll:" indicates a Collection by multiple artists.
