Music you purchase from the iTunes Store can sometimes have rather arbitrary genres (the "World" or "Classic" genres, for example, include anything from Latin jazz to Renaissance dances). Music files you import into iTunes will often not have any genre at all attached to them. As you add more music to your iTunes library, you will sooner or later have to get a grip on this genres melting potential, and either change the genre of albums to a predefined genre, or create your own genres - an unavoidable conclusion, we think, if you are a hardcore iTunes user, and manage all your audio entertainment from it.
Follow these steps to change the genre of a song:
Inside iTunes, find the track whose genre you want to edit (the easiest is to work in List View)
As you start typing a genre name for the track, iTunes will use the characters you typed so far to guess and pre-populate the genre label, as shown on the screenshot: iTunes will either use the "standard" genres of the iTunes Store, or the custom genres you have created in your iTunes library on the current computer. As soon as you finished typing the updated genre name, or as soon as iTunes has correctly guessed which genre you planned on changing to, hit Enter (or Return on a Mac) to change the selected track's genre to your new choice.Tip: Another useful aspect of creating your own, custom genres, is the ability to filter your music without interference: typing one of the standard genres like "Dance" will bring up unwanted, if not unexpected, results: (because the word "dance" is used in the track name, album name, etc.)
The music above was written over four centuries before "dance" was invented, clearly not the filtered result we intended. Making up your own words for custom genres allows you to avoid this problem!
Instead of changing / renaming the genre of one track at a time, here's how to change the genre of a complete album:
If your iPods are set to synchronize music with iTunes, you will also see your custom genres in the iPod.
