Wow - I don't remember a company "pivoting" so much, so often, and so drastically as the Turntable team has done. First it was a social DJ site/app, then they launched Piki but shut it down after less than a year [0], and now this. Kudos to them for not quitting - it takes a lot of resolve (and money) to try to break paradigms and move into new markets.
