yeah, CDDB is a bad hash for generating primary keys. the
up-and-comer I think is:
theirs uses more TOC data and a longer key (160 bits) than
CDDB which drastically reduces the chance for collisions.
I use a minor improvement on that for cataloging my own
collection (source available for the interested).
the safest thing is probably to invent a standard for
storing the whole TOC; it is actually not that much
data. then you can generate any key on demand.
