Here's How:
Open iTunes and highlight the song or songs you want to edit by clicking on it once. To highlight a group of songs, click the song at the top of the list you want to change, then hold down the shift key and click the song at the bottom of the list. This will highlight all the songs in between.
Once you have selected the song or songs you want to edit, do the following:
- Go to the File menu
- Select "Get Info" about halfway down the menu
This will pop up a window that lists all of the things you can edit about the song or songs you've selected. You can edit:
- The name of the song
- The name of artist
- The year the song was released
- The album name
- The composer of the song
- The track number, which determines what order the song plays in
- The genre of the song
- And a few other things
When you're done making the changes you want, click "OK" at the bottom of the window. If you want to edit the next song listed in your iTunes library, click the "Next" button.
NOTE: If you're editing a group of songs, you'll only be able to make changes that apply to all the songs. For instance, you can change the name of the album or artist or the genre of a group of songs. You can't, however, select a group of songs and then try to change just one song name, because you're editing a group of songs.
