Rdio's CEO, Anthony Bay, doesn't want Spotify knowing what it knows, and to that end, the music service is looking to break away from Echo Nest. However, the music intelligence company, recently bought by Spotify, is just one of several partners that Rdio taps for its music data, including Rovi. Spotify has previously said that it'll run Echo Nest as a "wholly-owned subsidiary" which should keep the data service relatively free from any meddling. In an interview with CNBC, Bay said: "We, probably like most people, have multiple sources of data that we use. So we will stop using that source of data [Echo Nest] and use other sources."
