An audio CD is a special kind of CD, and thus is given special
treatment by the kernel.  You cannot mount an audio CD, but really,
it's just that it is this way.  There is no reasoning for this
behavior.  Like in winduhs you can see the track numbers of audio CD
through explorer (I guess so, have'nt used winduhs since long :), the
linux kernel could have allowed mounting audio CD's and showed the
track numbers as files.  But it's immaterial anyway.

cdparanoia is probably using /dev/cdrom as your default CDROM device
(which should be a symbolic link to your actual cdrom device).
CD ripping requires special ioctl's to be sent to the cdrom driver,
and then the raw tracks are read directly from the cdrom device.

Mounting only makes sense when you want to use normal fileoperations
to the CD (like doing ls, cp, dd etc.).
