For OS X 10.8 and later. This applet will attempt to extract the CD Text information from the selected audio CD in iTunes and apply it to the CD's disc and track tags.
Some commercial CDs and commercial CD burning software (including iTunes) can use CD Text as a method of including text data on an audio CD. This data can include Artist (Performer), Album, Composer, Track Title, and Genre info. See the Read Me for more information.
In this example, all the tag data (except Year and Disc Number, which I supplied) are derived from the CD's CD Text.
