Prince is starting to remove his back catalog from music streaming services, with tracks disappearing from Spotify and Rdio so far. They’re still available on Google Play, Deezer and Tidal—though it’s not clear how long that will last.

Not to be outdone, Rdio has just announced a family plan that's basically like Spotify's. Families now get a discount of 50 percent on the premium subscription price for each additional member.

Rdio's new iOS app recommends music based on your listening habits. Hardly innovative, but useful.
