It would be great to define, or use predefined views, not
only the predifned Directory Tree.
So you can browse the data by metadata and show a
selection of fields.
i.e.:
1) view: all field: mp3-album, mp3-artist, mp3-title, etc..
2) view: artist, album fields:mp3-title, length etc..
Can you tell me how it should look like?
