Thanks for the pointer.  I didn't know anything about CDDB, etc.  So I
did some research on Google and now I know a bit more.  Then I did some
experimentation with my system.  I'm using "CD Player" that comes with
Gnome.  The documentation doesn't tell much but I noticed that it had a
"CDDB  Track Editor" with a "Save" button.  I guessed it was being saved
in a hidden directory in my home dir.  Sure enough, .cddbslave has files
for each CD it has ever found CDDB info on.  I removed them all and
disconnected the LAN cable and now the CDs that previously showed the
Artist/Title/Track info show "Unknown".  Plug LAN back in and rerun "CD
Player" and the info is back and the .cddbslave file is re-written!

So, yes, my player is getting it from some CD Data Base on the net.  I
wonder which one...  Gracenote, who apparently owns the original "CDDB"
says they don't charge for non-commercial licenses so that's probably
where "CD Player" is getting it but it might be "freedb.org".

Anyone know?

If it is possible to put this info directly on the CD, why wouldn't
everyone do it?  In a production environment (or even onesy-twosy) is
seems like it would be trivial once you figured it out and had the write
hardware.  So what if most players couldn't read it.  If it cost nothing
to add it, what's to be lost?
