want to log on without facebook

[kristensid]

I recently got Spotify premium and it was all working fine and then I had to switch my phone. I reinstalled spotify and it says that I created an account through Facebook. So on my iPhone I try to log into my spotify through my facebook login page. I type in my username and passcode and push send, of which the result is that I am redirected back to the Facebook login page. I would like to just eliminate the Facebook aspect of my account, and use the same email and keep all of the playlists I've already created on that account. How can I do this?
