An alternative that doesn't require a new algorithm is the CDIN system.
Please check out http://www.cdin.org/.
Regarding the CD Index algorithm: there have been several posts about
those extra zeros (since an MD5 hash is sensitive to them). I'm not sure
whether a change was resolved to be made or what, tho. Personally, I'm
not sure that I understand the reason for the change, but I bet it was
somewhere in the initial flood of email that ensued after the break of
the Slashdot story re: CDDB.
[ I would love for somebody on the CD Index list to educate me on the
rationale for the change... thx! ]
Cheers,
