Echo Nest + Rdio = Remember Pandora?

Something awesome is happening in the world of music and the web. But first, some primer.

Rdio is one of the few music subscription services that do a tremendous amount of things right, including having its robust Rdio API. For $5 a month, you can get all of the music you want, have collaborative playlists, share content to Facebook and Twitter, and keep up with what your friends are listening to. For $10, you can do all that and store the music to your phone for offline or higher quality enjoyment.

Echo NestThe Echo Nest API is a metadata service. A powerful and rich one, too. Tons and tons of information about tons and tons of songs. If you're developing anything involving music on the web, chances are you'll want Echo Nest somewhere at the core of it.

Pretty cool stuff. What if they got together? Peanut butter. Meet jelly.

Rdio and Echo Nest recently announced that they're teaming up to usher in the next generation of music apps. With Echo Nest's tome of metadata and Rdio's seemingly infinite music Library and streaming API, developers can do some very interesting things in the way of music apps.

"We're making the bet that music app developers are the future of the music business" Echo Nest CEO Jim Lucchese said in this Fast Company article.

Music Machinery's Music Maze is one of the first apps to utilize the new alliance's services to put together what can be described as a create-your-own-adventure playlist. A song is selected at random and based on the traits of that song, other songs that are similar, but can alter your playlist, are offered as next track selections. After playing with it for about 20 minutes, you really see the appeal here and then immediately tell your friends.

The music maze

Apps like Music Maze are just the beginning. Combining this level of detailed information with a mass of content is bound to bring us some great products. And maybe, out of a desire to stay competitive, it might also finally bring developers a Pandora API.
