Manu,

Not tested, but what's about:

<div instanceof="hmedia:Audio" about="#song">
   <span instanceof="hmedia:Sample" about="#song_sample"
   <a rel="hmedia:uri" about="#song_sample"
      href="http://www.bitmunk.com/sample/6011101"
      property="dc:title" content="Listen to a Sample">
   </a>
</div>

Ok, it does not visually render in the browser, 
but I does address your issue, right?

Cheers,
	Michael

>      <span property="dc:title">Listen to a Sample</span>
>   </a>
></div>

>generates the following triples (again, please correct if incorrect):

>   #song_sample dc_title Listen to a Sample
