There are several smaller pieces of Spotify news knocking about this week. The company has updated its Android app, with a key new feature being the ability to “share music with NFC on ICS” (ICS being the Ice Cream Sandwich incarnation of Google’s Android software). This means tapping phones with a friend to exchange playlists. Separately, Spotify has inked deals with hi-fi manufacturers Denon and Marantz to make its service accessible through some of their latest products – another sign of traditional audio firms adding Sonos-style features to stay fresh. Perhaps most significantly, though, it has emerged that Spotify is now allowing new US users to sign up with an email address, rather than forcing them to log in with their Facebook ID. The company tells Billboard it’s “just a small test of the user flow”.
