The only data written to a WAV file's metadata section from rekordbox is:
- IART: Artist
- ICMT: Comment

The rest is stored in the rekordbox database or an exported XML file. The exported XML data is as follows:
- Name

- Grouping
- Genre
- Comments
- Remixer
- Label
- Mix
(Plus additional system fields.)
