Once the new email account is =fully= active you will need to change your email address in your DreamLyrics profile also. To do this, log in as usual, and select 'My Stuff' (top of any page). Then select 'Profile' (top left). Overtype your new email address in the appropriate slots and press the 'Submit' button at the bottom of the page.
Now the fun starts!
To ensure security, the board will now email you with a new password to authenticate your new email. This is why it is important that your new email is fully functional =before= doing this.
Once you have the new password, you can revisit the site, login in with the new password you have been sent, and follow the path into 'Profile'. Now you can change your new password (by overwriting) to your old one or to something easy for you to remember. Remember to press the 'Submit' button at the bottom of the page.
