Then let's achieve it.
If the GUI programs are defiant then we can force success by command line.

For testing burn programs before buying the player you could let them make
a CD from your intended input files and let cdrskin inspect it. The
following run also creates a binary file cdtext.dat as wodim and cdrecord
would do too:

  $ cdrskin dev=/dev/sr0 -vvv -toc
  ...
  ... quite a lot of messages because of -vvv which we need to see the
      CD-TEXT ...

  cdrskin: NOTE : Wrote header and 828 CD-TEXT bytes to file 'cdtext.dat'

"control: 0 mode: 0" means that it is a stereo audio track with no
explicit permission to make a binary copy. With this permission it would
be "control: 2 mode: 0""
A data track would bear "control:" values 4, 5, 6, or 7.

The CD-TEXT display shows the text packs of the CD. The first byte is the
pack type. The title of the CD and the titles of the tracks bear type 80.
(Others are for performers (81), song writers (82), composers (83),
 arrangers (84), messages (85), disc id (86), genre id (87),
 a hidden remark not visible on players (8d), artwork registration codes
 "UPC/EAN" aka "Media Catalog Number" and "ISRC" (8e). 8f is for internal
 housekeeping of CD-TEXT.)

Most important for the player's menu will be the track titles.


Have a nice day :)
