Audio CD With Added Data Tracks
Hybrid-CD also refers to audio CD which also includes a data track storing MP3 (or other digital audio compression format) copy of those CD-DA tracks. Before the introduction and subsequent popularization of iTunes and the iPod, such discs were popular for sharing music on compact disc without requiring the recipient to extract and encode the CD-DA themselves — a technical and perhaps time-consuming process on older computing hardware. However, with the advent of faster computing hardware and vastly simplified automated extraction and encoding tools (e.g. iTunes, Rhythmbox, etc.) and the lack of an automated hybrid feature in that very same software, popularity of such hybrid CD has subsequently declined. Furthermore, the legal status of such discs poses economic frictions in that they may be interpreted as two copies of a copyrighted work. However, such hybrid discs do remain in a commercial setting as a digital rights management enforcement technique, where encrypted compressed copies of the digital audio are provided with proprietary software for listening in a computer disc drive, while the CD-DA is included for playback in stand-alone CD players.

Famous quotes containing the words added, data and/or tracks:
“Let us not underrate the value of a fact; it will one day flower in a truth. It is astonishing how few facts of importance are added in a century to the natural history of any animal. The natural history of man himself is still being gradually written.”
—Henry David Thoreau (1817–1862)
“Mental health data from the 1950’s on middle-aged women showed them to be a particularly distressed group, vulnerable to depression and feelings of uselessness. This isn’t surprising. If society tells you that your main role is to be attractive to men and you are getting crow’s feet, and to be a mother to children and yours are leaving home, no wonder you are distressed.”
—Grace Baruch (20th century)
“Our law very often reminds one of those outskirts of cities where you cannot for a long time tell how the streets come to wind about in so capricious and serpent-like a manner. At last it strikes you that they grew up, house by house, on the devious tracks of the old green lanes; and if you follow on to the existing fields, you may often find the change half complete.”
—Walter Bagehot (1826–1877)
