Spotify and The Echo Nest today announced integrated APIs, making it easier for Spotify app developers to tap into The Echo Nest for all of the deep musical intelligence they offer. For customers, this partnership should lead to more synergy opportunities between recording artists and the music labels and their fans.

The Echo Nest is integrating Spotify IDs into a resolution service called Rosetta Stone. This unique technology translates song and artist identifiers between music content and data APIs including Twitter, Facebook, Lyricfind, MusixMatch, 7Digital, EMI, Free Music Archive, MusicBrainz, Rdio and Seatwave, and also makes it easy to leverage The Echo Nest’s core music discovery and personalization features within a Spotify app.

From there, any Spotify app that seeks to leverage the wealth of third-party data using Rosetta Stone will enjoy the ease with which that data can be incorporated.

For example, as songs play, an app could display lyrics, Tweets and Facebook updates from the artists being played alongside ticket offers. A radio app, in another example, could pair the buzziest bands with reviews, biographies, and the option to branch off to a new station based on any song or artist. It all happens without extra work on the part of the developer through the magic of Rosetta Stone.

Spotify+The Echo Nest

Even before this partnership, Spotify users enjoyed the power of The Echo Nest+Spotify. In addition to The Echo Nest powering the official Spotify radio, several successful third-party apps run outside of the Spotify client, such as SpotON Radio and Echofi.

Headquartered in Somerville, Massachusetts, The Echo Nest was originally the work of the MIT Media Lab. The company’s primary purpose is to provide music recommendation, playlist generation, acoustic analysis, music identification and data feeds to third-party developers.

Based in Stockholm, Sweden, Spotify first arrived in 2008 in Europe. In 2011, it arrived in the U.S. and offers streaming from a range of major and independent record labels, including Sony, EMI, Warner Music Group, and Universal.
