Imagine what your iTunes library would be like if all your songs just had random characters for their song, artist, and album names. You'd never find what you want to listen to. But even if your iTunes library's tags are mostly correct, any erroneous tags may prevent you from finding your music. If an artist's name is spelled wrong, for instance, or if there's a typo in a song name you won't find your favorite tunes when you search in iTunes. And if you've left some tags blank, some of your music won't display in certain views.
