can anybody explain what The Echo Nest is? And why it is important, that SHS is linked to it?

On March 6, 2014 Spotify announced that they had acquired The Echo Nest.
The data powered music solutions for customers such as MTV, Island Def Jam, BBC, MOG, Warner Music Group, eMusic, Spotify, Rdio, Clear Channel, VEVO, Nokia and Thumbplay.
The Echo Nest was acquired on March 6, 2014 by music streaming service Spotify.
The music intelligence agency functions to help Spotify curate personalized music recommendations that are driven by algorithms. The Echo Nest is the driving force behind the playlists professionally curated on Spotify. To generate individualized Discover Weekly playlists as well as recommend suggestions in the ‘Discover’ section of Spotify’s home page, individualized for every subscriber, the Echo Nest collects data on a user’s listening habits and uses it to predict what music they will enjoy the most.
