One of the biggest (but dumbest) things is I signed up for Spotify with Facebook...and need it to log in.

I'm too lazy to like transfer all my playlists and liked songs to a new account.

You wouldn't have to transfer to a new account, you'd just have to create the account and link it, then remove the Facebook connection.[1]

I don't remember how but I was able to remove FB from Spotify a few years ago. Maybe had to set a password and/or contact support.
