The Echo Nest today announced that it will be integrating its API with Spotify, effectively allowing app developers to use the Echo Nest's vastly influential music intelligence algorithms in order to create apps within the Spotify model.

All 12 New Spotify Apps Come From Record Labels

The Echo Nest's platform is behind many of the biggest music apps on the market - the company has partnered with Twitter to allow for tweets to be easily embeddable into apps, with EMI to simplify music licensing for EMI artists, and powers everything from Clear Channel's iHeartRadio, eMusic Radio, Nokia's MixRadio, Rdio, and even Spotify's Radio app.

Here Come The Spotify Apps

With all these partners on board, the Echo Nest is developing an intricate web of music listening knowledge, and app developers that want to launch on Spotify's platform can use that information to help build playlisting, radio, music recommendation and music discovery into their apps, making them more versatile and dynamic.

In the first three months after the launch of Spotify's app platform (which they have described as their "biggest announcement yet"), users have listened to over 1,500 years worth of music using them, and this integration seems set to only ramp up the app development. Last week, the company announced a round of 12 new apps, all from record labels, and yesterday Songkick announced its Spotify app, launched in December, had already brought them 100,000 new users.
