The MixRadio C# SDK is compatible with Windows Phone 8, Window 8 and .Net Portable Class Library apps. The SDK will power 'launchers' that interact within a 3rd party app, as well as an API to retrieve song data. Nokia MixRadio is a free music streaming service that allows listeners to create personalized radio stations by rating songs positively or negatively. Over time, the service learns what the listener prefers and adapts. Users can start by creating their own mixes using their favorite artists or by using mixes that have already been put together by Nokia MixRadio's music experts. The Nokia MixRadio APIs allow users to integrate the service's music discovery and music information retrieval services into their own applications.
