Ultima IV: Quest of the Avatar

"Shrines" is also played when peering at a gem
to get a map of the current surroundings.
"Lord British" is also played at the end of
the game.

I suspect that track 9, which is unused in the
Apple II version, was supposed to play when
using the "Hole up and camp" command. That's
where it plays in the Sega Master System
version at least. That this song is included in
both the dungeon (MUSD) and (MUSO) files,
which are the only environments where camping
is possible, but not in the others also speaks
for this hypothesis.

I refrained from looping tracks that in the
game only loop with a long pause in-between
(tracks 1, 3 and 4).
