Tired of seeing so many tunes named Untitled? You have a couple of different ways to change song titles in iTunes—for example, to enter a song's real name or to fix a typo.
In the song list, click the text you want to change, wait a moment, and then click again. The title now appears highlighted and you can edit the text—just like when you change a file name on the desktop.
Another way to change the song's title, artist name, or other information is to click the song in the iTunes window and press Ctrl+I (⌘-I) to summon the Get Info box. (Choose File→Get Info if you forget the keyboard shortcut.) Click the Info tab and type in the new track information.
Once you've got a song's Get Info box on screen, use the Previous and Next buttons to navigate to other tracks grouped with it in the iTunes song list window. This way, if you want to rapidly edit all track information on the same playlist, on the same album, and so on, you don't have to keep closing and opening each song's box.
