Me either. What quality setting did you use?
Soul Coughing - Ruby Vroom, entire album, one file per track, quality 4
bzip2'ed oggs save 0.181% over oggs alone (less than two-tenths of 1%)
Grits - The Art of Translation, entire album, one file per track, -q 4
bzip2'ed oggs save 0.15% over oggs alone
The Matrix - Music from the Motion Picture - entire album as one track, -q 3
bzip2'ed ogg saves 0.183% over the ogg alone

A girl and a boy bump and her handkerchief drops -- surely another accident.
But when a girl gives a boy a dead squid -- *that had to mean something*
