Senzari, a cutting-edge music technology company, has launched MusicGraph, a knowledge engine for music that is modeled after a semantic network and powered by an API with an architecture that is similar to Facebook Open Graph Protocol. Senzari has also released a MusicGraph API which allows developers to retrieve objects from the MusicGraph.
Rumblefish, champion of what is good and just and legally musical, will help you change your tune for the better. This company has produced a music licensing API so that you can add copyrighted songs to your YouTube videos. Of course the concept can be applied more widely and liberally. Rumblefish has even devised custom license ‘portals’ that present licensing options based on the intended use of the music. This implies that the agreement and cost of licensing a track could be more expensive depending on where and how it is used.
