actually, believe it or not, all CDDB does is use track time, number, and
order to determine a 'unique ID' for an audio CD - there's nothing else in
the 'red-book' audio spec to go on. But it turns out that that is enough -
the chance of having two CDs with the same number of tracks, with the
*exact* same lengths, in the same order is extremely unlikely.

ya got me there - you sure it didn't connect you? I'm pretty sure it needs
to connect to do the lookup.

or you could check out musicbrainz - this began life as CD Index
(http://www.musicbrainz.org) and was started in a similar moment of outrage
when CDDB went proprietary. It uses the GNU openContent licence which means
no-one will ever be able to take the info private - they're also planning a
system in which anyone can run their own mirror. They're using a moderation
system to improve the quality of metadata, which will include a lot more
info than basic artist-album-track info. (follow the Metadata Initiative
link on their site for more info about this.)
i met lead developer Rob Kaye at the P2P conference - he definitely got the
nod for best hair in show:
