I had my Facebook account linked to my Spotify account. I didn't create an account using Facebook, but linked them later on.

Even when I had a Facebook account linked, I could still login to Spotify using a username (a bunch of numbers) that I was able to dig out from the settings at some point.

I recently deleted my Facebook account, and everything went quite well. The app said my playlists was created by user "null" (they fixed this after a while and now displays the numbers which makes my username), but other than that there's been no changes. So, just deleting your Facebook account and let Spotify deal with it seems to work, but it require you to know the username (and password. I don't know how I got that, maybe it was the same password as the one I used before linking my Facebook account).
