Can I change me email for my Apple Music account?

Hi,

I was trying to register for Apple Music, and I confused the email addresses that are meant to entered. I entered my school email address in the place where I am supposed to have a regular email address, and now where I am meant to enter my school email address, it's saying that it's already in use. Is there a way to update or rectify this?

1. Sign out of every Apple service and device that uses your Apple ID.
2. Sign in to your Apple ID account page.
3. In the Account section, click Edit. Under your Apple ID, click Change Email Address. You might be asked to answer one or more of your security questions.
4. Enter the email address that you want to use as your Apple ID. A verification code will be sent to your new email address.
   
5. Enter the verification code from the email into the fields provided and start using your updated Apple ID. Didn't get the email?
6. Sign back in to all Apple services with your new Apple ID.

After you change your Apple ID, you need to use your new sign-in information with all Apple services that you use.
