More than likely you never heard of ‘The Echo Nest’, shoot, I’m a super geek and I never thought to find out what’s the force behind(API) Internet Radio apps like Pandora(in the #1 position), Spotify, Rdio, Twitter Music, and I assume iTunes radio, Songza, and more, but now we know it’s the Echo Nest, and we now know it’s own by Spotify because they just acquired it! What does that mean for your fav radio app though?!
