Nice! One thing unclear to me is why the location tags
in <xspf.xsl.out> are empty? Also shouldn't it be
extracted from <listenurl> instead of the mount attribute?
Extra problem is, that empty location tags are not allowed
in XSPF so they would have to be omitted then.

You mean losing the structure inside the annotation tag?
You could in addition create an extension, that holds
the same elements that the icecast stats do.
What I have in mind looks like this:

   <track>
     <extension application="your_URI_here">
       <server_description>copied over</server_description>
       <server_name>copied over</server_name>
       [..]
     </extension>
   </track>

That way you can have best of both worlds: Informative
<annotation> and preservation of the old structure.
In case you like the extension idea let us know if
you need help defining it.
