Spotify has seen a huge increase in traffic from Facebook since implementing the Facebook Connect technology in its service earlier this year.”Facebook is now the biggest referrer of traffic to Spotify, and they have seen a 4x increase it he amount of traffic coming from Facebook,” said Facebook's Developer Network director Ethan Beard, in an appearance at the LeWeb conference in Paris.His answer came in response to a question about whether Facebook plans to launch its own music service. Beard reiterated that there are no plans, since the company would rather be the platform for others.”We are in the music space to the extent that we offer a platform that anyone can build on,” he said, before saying Facebook expects the social disruption that has happened in the games industry – where it's been suggested that Zynga is more valuable than EA now – will spread to other industries.”We think what happened in gaming is going to continue happening across a variety of industries and verticals,” he said. “We think you'll see those industries rethought around social, and new leaders emerge.”Spotify has previously said that after implementing Facebook Connect, its daily rate of premium subscriber signups doubled, despite the fact that a premium account was not needed to use the social features.
