Without knowing your password there's not much you can do. What I'm going to recommend is getting in touch with support through this from. This is the "anonymous" contact form, so you'll be able to input which email you want them to reply to. For the form to work, make sure you are completely logged out of Spotify.com, otherwise it will automatically use the email of the account you are logged into! Please note that you will most likely receive an automated email back from support directing you to the forums or the FAQ page; just ignore that, and reply back directly to that email (even if it comes from a no-reply address), and support should help sort your issue out as soon as they can.
