* e.g. "Various Artists" for compilation albums.
* artist -- main creator of the work
* comment -- any additional description of the file.
* composer -- who composed the work, if different from artist.
* copyright -- name of copyright holder.
* date -- date when the work was created, preferably in ISO 8601.
* disc -- number of a subset, e.g. disc in a multi-disc collection.
* encoder -- name/settings of the software/hardware that produced the file.
* encoded_by -- person/group who created the file.
* filename -- original name of the file.
* genre -- <self-evident>.
* language -- main language in which the work is performed, preferably
* in ISO 639-2 format.
* performer -- artist who performed the work, if different from artist.
