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.
AudioBoo brings the familiar tape-recorder type interface to the web with all the fixings. Take your audio recording, add a picture, a location, put it in a social context, throw in popularity ratings and you have AudioBoo. The simplicity and social aspects of this service make a great platform for podcasters while providing another avenue of media discovery for users. But it's new and still changing. If you're feeling like an adventurous explorer, ready for twists, turns and surprises, jump on in to the AudioBoo API.
GoodGuide is a service that we have been using as a family for a while. It attempts to analyze a product holistically & scientifically to produce a simple 1 to 10 rating of its "goodness." I am personally satisfied to see that the GoodGuide API will share this data with the world.
