How to change email account in youtube ?

I want to change email account in youtube.In Account settings ,Email options under Email address it is mentioned as :

You signed in via Google, so you should click here to change your Google email.

When i click that link it directly goes to — https://www.google.com/accounts/EditEmail

That is the settings page in gmail…There i cant change the email for youtube.

It is confusing…
I searched about this,but no solution.Most of them are saying,the only way is ,To create a new youtube account. ???

If there is no way to change email account for youtube except to create a new account,then why they mentioned that option under Account settings ,Email options under Email address ?

Anyone knows How to change email account in youtube ?
