How to Play CD Tracks in iTunes
You can use iTunes to play the songs on a CD. If you don’t want to rip music CDs and store the tracks in your iTunes library, you can still use iTunes to play tracks right off the CD without importing them.
Just insert any music CD — or even a CD-R that someone burned for you — into your computer. After you insert the CD, iTunes displays a dialog box that asks whether you want to import the CD into your library right now. Click Yes or No, depending on whether or not you want the CD info imported. Either way, click the Play button and iTunes plays your CD.
If you’re connected to the Internet, iTunes accesses the Gracenote CDDB for song information while you are answering the import question, so that after you click Yes or No, iTunes presents the track information for each song automatically, as shown here. (Gracenote CDDB is a song database on the Internet that knows the track names of most commercial CDs but not homemade-mix CDs.)
Eject a CD by clicking the Eject icon next to the CD name in the Source pane or by choosing Controls→Eject Disc. You can also right-click the CD name and choose Eject from the contextual menu that appears.
