Music singles

[cjcodeproj]

Singles should have a simple XML structure.

<content>
 <single xmlns='(namespace)'>
  <elements>
    <song id='song01'>
    </song>
  </elements>
 </single>
</content>

Here, a single is essentially an album, however it does not have a title, catalog, or classification elements.

Ticket #125 should probably be disregarded.

There should be no effort to identify an album as either an extendedPlay or a longPlay because that status can already be determined by the number of tracks, or total time length of the content.
