There have been moves by the [[recording industry]] to make audio CDs (Compact Disc Digital Audio) unplayable on computer [[CD-ROM]] drives, to prevent the copying of music. This is done by intentionally introducing errors onto the disc that the embedded circuits on most stand-alone audio players can automatically compensate for, but which may confuse CD-ROM drives. Consumer rights advocates as of October 2001 pushed to require warning labels on compact discs that do not conform to the official Compact Disc Digital Audio standard (often called the ''[[#Standard|Red Book]]'') to inform consumers which discs do not permit full [[fair use]] of their content.

In 2005, [[Sony BMG Music Entertainment]] was criticized when a copy protection mechanism known as [[Extended Copy Protection]] (XCP) used on some of their audio CDs automatically and surreptitiously installed copy-prevention software on computers (see [[Sony BMG copy protection rootkit scandal]]). Such discs are not legally allowed to be called CDs or Compact Discs because they break the ''Red Book'' standard governing CDs, and Amazon.com for example describes them as "copy protected discs" rather than "compact discs" or "CDs".
