\page p_propertymapping Mapping of Properties to Various Formats

- If no mapping is given for an %ID3v2 tag, a TXXX frame will be used with the
  key as a description.
- Vorbis Comments are not included in the table because they use the names from
  the *Key* column.
- %APE tags will also use these keys unless another name can be found in its column.
- %Matroska tags will also use these keys unless another name can be found in its column,
  additionally, the target level is listed, e.g. /50 for Album, /30 for Track (default).
