The PlayStation 4 might not play CDs (yet) and an official YouTube app is still MIA, but that doesn’t mean music and music videos are out of reach. Vidzone has finally taken its streaming app into the next generation, and, unlike Music Unlimited, it’s free. Much like its previous-gen counterpart, the video application offers concerts, interviews, custom playlists and even crams the PS4′s native social-features in for good measure. You can share screenshots of what you’re watching to Facebook and Twitter, for instance, and recent activity in the app also populates the “what’s new” activity feed on your friends’ consoles. Unless you want your Battlefield 4 clan to know you went on a lengthy Ke$ha binge, however, we suggest turning that setting off.
