Would be great some inprovements in the logical view to
support best "classical" music stuff. (My preferred stuff)
Some metadata that is prior to album in id3 tag, thus
you can have the opera "Rinaldo" and inside the three
Albums (Rinaldo CD1, Rinaldo CD2, Rinaldo CD3).
This metadata could be named case, work, or something,
doesn't matter.
This metadata is made mapping some data how album
stuff, but it can be more complex.
In XML i mean this:
<case id="Rinaldo">
<album id="Rinaldo CD1>
<track/>
...
</album>
<album id="Rinaldo CD2/>
<album id="Rinaldo CD3/>
</case>
