If there is a well documented pre-existing standard that offers the
functionality we desire - I can see no reason to invent something
else. Adding itunes support sounds like a clincher to me.

> >>songs-offset:
>DH> ""
>DH> "song title",filename
>DH> "song title",filename
>DH> ... (alphabetically sorted by song title)
> >>albums-offset:
>DH> "SONGS",
>DH> "album name", song-index 1, song-index2, ...
>DH> "album name", song-index 1, song-index 2, ...
>DH> ... (alphabetically sorted by album name)
> >>artists-offset:
>DH> "ALBUMS","SONGS"
>DH> "artist name", album-count, album-index 1, album-index 2, ... song-index1,
>DH> song-index2, ...
>DH> "artist name", album-count, album-index 1, album-index 2, ... song-index1,
>DH> song-index2, ...
