If you are referring to the way computers display the contents of a commercial audio CD, this is not based on data files on the CD. It's based on the sequence of timing of tracks on the CD. The CD-player program sends the number of tracks on the CD and the duration of each track to the database through the Internet, and the database service returns the title of the CD and of each track.
