Backbone forms the core of the new, dynamic, realtime Rdio web and desktop applications. With Backbone as a foundation, the web interface was rewritten from scratch so that all page content can be loaded dynamically cramps no period smooth transitions as you navigate. Backbone makes it easy to move through the app quickly without the reloading of scripts and embedded videos, while also offering models and collections for additional data manipulation support.
