4.4. Music CD identifier
This frame is intended for music that comes from a CD, so that the CD
can be identified in databases such as the CDDB [CDDB]. The frame
consists of a binary dump of the Table Of Contents, TOC, from the CD,
which is a header of 4 bytes and then 8 bytes/track on the CD plus 8
bytes for the 'lead out', making a maximum of 804 bytes. The offset
to the beginning of every track on the CD should be described with a
four bytes absolute CD-frame address per track, and not with absolute
time. When this frame is used the presence of a valid "TRCK" frame is
REQUIRED, even if the CD's only got one track. It is recommended that
this frame is always added to tags originating from CDs. There may
only be one "MCDI" frame in each tag.
