Most of the examples that were gathered for hAudio were from music
service websites and music blogs. To help us make progress, this round
of haudio focuses on just albums and tracks.

We tried talking about playlists, podcasts, top-lists and others, but
those were slowing the discussion down. There is a clear answer to how
we support playlists, podcasts, and top-lists in the future... we add
the property to haudio. haudio has been designed in such a way as to
support that if it is ever needed.

We can support playlists, podcasts and top-lists with the current
ITEM+HAUDIO or ITEM+TRACK or TRACK+HAUDIO proposals, as long as we don't
make ALBUM mandatory (which is the direction in which the discussion is
going):

<span class="haudio">
 <span class="fn">My Playlist</span>
 <span class="item haudio">
  <span class="position">1</span>
  <span class="fn">Nagasaki Nightmare</span>
  <span class="album">Best Before 1984</span>
  <span class="contributor">Crass</span>
 </span>
 <span class="item haudio">
  <span class="position">2</span>
  <span class="fn">The Classical</span>
  <span class="album">Hex Enduction Hour</span>
  <span class="contributor">The Fall</span>
 </span>
</span>

However, that is beyond the scope of the current discussion, which is
just albums and the contents of those albums (tracks).
