I actually refused to use Spotify for years because they required Facebook login. I gave in eventually as Rdio lost to Spotify in the market. Like many, though, I am deeply concerned about Facebook's policy direction and leadership. I did disconnect my Spotify account from my Facebook account the hard way (with customer support) a few months ago.
In general I am enthusiastic about federated signin, but I don't want to do business with Facebook.
