No Im wrong hAudio *can* use rel="copyright"

http://microformats.org/wiki/rel-faq#Are_rel_attributes_and_linktypes_in_general_just_document_to_document

"Are "rel" attributes, and linktypes in general, just document to document?

The vast majority of the rel values defined in HTML4 are from a document 
to a document. rel="stylesheet" is a bit of an exception, as it from an 
HTML document to a style sheet, which is more like a set of styling 
rules and instructions than a "document" in the classical sense.

Two more notable exceptions are rel="copyright" and rel="bookmark" which 
describe the relationship from the current document to (potentially) 
only part of a document. "

Proposal:

change rel="licence" to rel="copyright"

I would have proposed rev="copyright" but rev is depreciated in 
Microformats (which is a shame in this case because it looks like 
something hAudio needs)
