CD text is encoded into the structure of the CD itself. It is displayed by most car CD players, and some domestic players. It may not show up on your computer unless you have an extra program such as WMPCD Text. And if you use ITunes or another download organiser your new CD tracks may be hijacked and given new names if you haven’t yet registered them with the app. This is because the app doesn’t read CD Text, but uses track length to guess the track’s identity.
