why doesn't itunes provide the track names when I import my CD?

iTunes uses the Gracenote service for providing CD information. If this is not a standard commercial CD it won't be in the database unless you entered it there originally. If it is a commercial CD it is possible the service is temporarily down, or you may not have your preferences set to connect to the database when a CD is inserted. We really need more background from you.

To re-identify an incorrectly identified CD: "Insert the CD and select it in iTunes, then menu Advanced > Get CD track names. It should requery the Gracenote database and let you pick the correct album." - https://discussions.apple.com/thread/4101761?answerId=18901866022#18901866022 - Newer versions in upper right hand corner, Options>Get Track Names You can also do this at a later time after ripping the CD: iTunes 11 for Mac: If you don’t see song information - http://support.apple.com/kb/PH12280
