There was a moment when Turntable.fm was seemingly ready to usher in an era of social music, with virtual DJs leading the way. Unfortunately, that moment has passed; in light of a shrinking audience and high operating costs, Turntable.fm has announced that it will shut down its DJ service on December 2nd. The company will instead focus on Turntable Live, its social platform for streaming real-world concerts. It's a sad day for musical tastemakers, although the company is going out of its way to support fans. Users can export their playlists and tracks to services like Spotify, and the company is promising both a commemorative t-shirt as well as a "last day" party on the 2nd. If you have fond memories of spinning tunes for friends across the country, we'd suggest making room in your calendar.
