One Way: (On Windows XP) Go to the folder where they're stored (ie: c://program files/Andie's Music), Open the folder, and then right click on a song - go to to the bottom, click "Properties" (button on the bottom), then go to "Summary" (tab on top).
That's your metadata - click twice on anything you want to change - it will highlight as if to copy, backspace and type in the correct information.
You can also use Windows media to edit your metadata. I'm not so good on that - I do it, but I have to click and search around a lot.
I'm kind of anal-retentive about the metadata, so I try to get it perfect right when I import the CD, before I move it into the folder that Zune uses. If you're like me, however, you now have thousands of songs on your drive - to go through ALL of them might make you want to snatch all of your hair out, and commit yourself to a mental institution. ![Wink [;)]](/emoticons/emotion-5.gif)
