Can't Log in with Old Facebook Account

[GravyTrain]

Originally signed up for Spotify with facebook, got Premium, was very happy. Eventually I deleted that facebook account but Spotify was still working perfectly. I made a new facebook and tried to link it to Spotify but couldn't.

I logged out and tried logging back in with just email, but found that none of my saved songs or playlists were there (no premium either). It was an entirely new account.

I still have my original account with all of my music logged in on my phone. How do I log in to my original account on my desktop after having deleted the facebook with which I signed up?
