CD-Text is a rudimentary metadata format used on audio CDs, and is like tags in computer audio files. Unlike other CD metadata sources, the information is not in an external database, but is actually encoded on the CD itself, in the subcode channels.

Very few commercial CDs have CD-Text data, and quite often, the data they do have is erroneous, incomplete, or poorly formatted.

Reading and writing CD-Text is not universally supported by players, drives, and software.
