It's not that hard to start playing Just Dance Now -- you only have to download and install the app. Samsung, however, is making it easier to access on its smart TVs by adding the app to its new Smart Hub interface. The Smart Hub gives you quick access to content from different sources like Netflix, YouTube, Hulu and Amazon Prime Videos, eliminating the need to jump from one application to another. You'll be able to access Just Dance Now under games, and you can even pay for a subscription through Samsung's billing system.
