It would have a small iso9660 data or udf session if so.

Some versions of that disc are certainly mangled. Its a disc I did
actually take a look at a long time ago as it was causing some IDE CD bug
reports which turned out to be CD firmware crashing not Linux. It amusing
played just fine/ripped just fine on an HP drive.

I would guess that the behaviour you see depends upon the way the drive
is queried or what the tools happen to do. Its also possible some windows
audio grabbing tools have hacks to defeat the copy protection on the
discs. For obvious reasons we can't ship such hacks in Fedora because US
legislators believe that the music industry is more important than the
people.
