I want to make copies of my CDs and add CD-TEXT because my car cd player can read that. How do I do it?

It is done with the cue sheet, you (or EAC) can add TITLE and PERFORMER tags (enable it in EAC options). If you want to burn with EAC, you will also find some CD-Text options in EAC options and don’t forget to activate it in the Drive options. In the Layout Editor, you could also still change title and artists.
