Nice. I have a somewhat simpler solution, since I'm less tag-happy than
you are. I use files called Manifest that look like this:

A Current 93
L Current 93/Michael Cashmore/Christoph Heeman
D 1999
01 An Introduction to Suffering
02 All the Pretty Little Horses
03 Calling for Vanished Faces
04 The Cat Is Dead
05 Untitled I
05A Michael Cashmore
06 In an English Garden
07 Untitled II
07A Michael Cashmore
08 The Flower Is RedRobed
09 A Silence Song, Silent
09A Michael Cashmore
10 Et in Arcadia Est
11 Moonlight, or Other Dreams, or Other Fields
12 Judas as Black Moth
13 Lazy Moon Part I
13A Christoph Heeman
14 Lazy Moon Part II
14A Christoph Heeman

Here, the A line is the default "artist" for the CD's tracks, which can
be overridden by a track-specific artist line (such as 05A, 07A, 09A,
13A, and 14A above). L is the title of the album, D its date (which can
again be overridden on a per-track basis, though the above doesn't have
an example of that). All this is used to generate oggenc command lines,
using the A or ##A line for the -a option, etc.

Additionally, the track title is munged by a sed script to generate a
Unix-friendly output filename by replacing spaces with underscores and
replacing or stripping out characters that are meaningful to the common
Unix shells (I hate having to remember to escape such things at the
command line).

Unlike yours, the above file is not sourceable from a shell script; my
"parser" looks like this:

line ()
{
    grep "^$1 " Manifest | cut -d " " -f 2-
}

which obviously isn't exactly fast, since it has to be called several
times for each track, but on the other hand, actually encoding the
tracks takes 99.9% of the time, so the speed of the parser is
insignificant.
