Data Type



This attribute is compatible with the ID3 frame, MCDI. The ID3 specification for the MCDI frame requires that only one such frame exist per file and that a valid TRCK frame exist. The metadata editor does not perform any validation for these rules. Also, the size of WM/MCDI is not limited to 804 bytes, as is the MCDI ID3 frame.
