my account has been stolen. Someone has logged in and changed my email and password. I can still log in via facebook, but obviously can't change the email without their new, fraudulent password. I've contacted spotify using the email generated when account settings are changed, in addition to using the contact form, but I figured this couldn't hurt to draw attention to my case.
edit: got my account back through my own methods :) don't you just love it when hackers are really just script kiddies?
