D'oh.  You're right of course.  I suppose my idea would probably blend 
all the tracks together into one long track.

I assume the audio is available from the block device for most newer 
drives tho, because most newer drives support
cdda extraction (w/o the digital -> analog  -> digital evilness), and I 
assume tho do that through the ATAPI interface.

I don't know, maybe the cdrom driver uses an ioctl interface to 
manipulate the drive and access various audio tracks
and things..
