No search engine that I know of does CC aware indexing of audio. I
suspect the first one that does will look at descriptions of http URLs
returning audio files rather than URNs with hashes of the files. The
latter is primarily intended for use by P2P clients to verify that the
URL they have a reference to is talking about the file with the
reference ... turned out to not be a big use case.

It could be explained much better. Both have the same statement
(subject, predicate, object), first as RDFa, second as something
N-Triples like. The page needs to be rewritten for clarity.
See http://www.w3.org/Submission/2008/SUBM-ccREL-20080501/ for a
longer and hopefully clearer exposition. For a music site, I'd to
start with recommend simply something like
<a href="http://creativecommons.org/licenses/by/3.0/" rel="license">CC BY</a>
