CDTEXT is a standard for encoding certain text fields onto a CD, including track title, performer, composer, and a short message.Â  While a supported standard, very few consumer CD players actually bother to implement this (it seems to be most notably used in car stereos), and only a few computer-based CD playing programs pay much attention to it (one or two will sue CDTEXT, if present, only if Gracenote info cannot be found).Â  Itâ€s not a bad idea to have it on your CD, and it certainly wonâ€t hurt anything, but itâ€s not something to lose sleep over, either.
