I was reading that people had similar problems, but it didn't seem to be exactly what I have
Here is what happened: When Spotify came out it was only possible to sign-up with your facebook account, so that was what I did. My email address I used for facebook back then was my old email address (let's say "firstname.lastname@example.org").
So when it was possible to register to Spotify with a new account (without using facebook) I did that (because I was prefering that from the start anyway) and started using Premium with that account.
I registered this new account with my new and actual email address ("email@example.com"), as I don't want to use my old one anymore. I completely stopped using my old Spotify account (the one that was hooked with facebook).
Now that I want to get rid of my old email address I changed the address at facebook as well to "firstname.lastname@example.org", but AFTER I registered my new account here at Spotify. So now when logging in with my new Spotify Premium account I cannot change any settings, as it's telling me my email address is already in use for a another acccount (with the one, that is hooked to facebook). Also at times I get mail from Spotify to me "email@example.com" email address now, but this mail is intened for the old Spotify-facebook-account. It's all kind of mixed up now, even sometimes when logging in.
I would love to just get rid of my old Spotify account, the one that IS connected to facebook – I'm not using it and I really don't want these accounts to be hooked anyway. How can I do that, or what other solutions are there?
Thanks in advance!!
