How to Retrieve Song Information from the Internet in iTunes
iTunes retrieves song information (the song's name, the recording artist, the album it was on, and so on) from the Internet. You can set iTunes to get the information automatically, or you can retrieve it manually. The online database available for iTunes users holds information for millions of songs.
Preventing iTunes from getting song information automatically
By default, iTunes automatically looks for song information on the Internet. You can disable this feature:
Choose iTunes→Preferences (Mac) or Edit→Preferences (Windows).
The iTunes Preferences dialog box appears with buttons along the top.
Click the General tab (if it's not already selected).
The General preferences appear.
Deselect the Automatically Retrieve CD Track Names from Internet option.
When you turn this feature off, iTunes doesn’t retrieve the information, but you can retrieve it manually.
Getting song information manually
Any time you connect to the Internet, you can retrieve song information. After you connect to the Internet, choose Advanced→Get CD Track Names.
Even if you automatically connect to the Internet, the song information database on the Internet (Gracenote CDDB) might be momentarily unavailable, or you might have a delayed response. If at first you don’t succeed, choose Advanced→Get CD Track Names again.
