Social Network : Spotify users get a 'private listening' mode, Facebook account still required

It may not be addressing complaints from those bemoaning the need for a Facebook account in the first place, but Spotify is now at least giving folks an easy way to listen to what they like without broadcasting it to their friends. That comes in the form of a new "private listening" mode, which can easily be turned on and off at will -- the other option is to unlink your Facebook account completely.
