Computers use an online database to display CD information, the most common one is known as Gracenote, a more detailed article on Gracenote can be found here Gracenote CD Database and CD-TEXT.
Tunes and Windows Media Player DO NOT read and CD-Text embedded on the actual CD, at all! This is common for all computer CD player software.
When the CD information is displayed on a computer, the info is coming from an online database. The database is usually Gracenote (the more common) or AllMusic.
The Gracenote database serves CD information to: iTunes, WinAmp, Quintessential Media Player, and Finder (Mac OS). The AllMusic database serves CD information to: Windows Media Player, Rhapsody, and Real Music Player.
Registration on these databases must be completed by you, the client, rather than us as no extra information is added to the CD for them to work.
You can find further information on how to submit your CD on the below links.
