Interesting. I know CDs have been around a very long time (as technology
goes) but it's still amazing that the developers didn't anticipate that
basic need. Are new players being designed to read it so that someday
when all the "old" players are dead, CD publishers could start including
it? The CDDB technique, as cool as it is, sure seems like a brute force
kludge compared to just having the CD itself tell the player what it
needs to know.
