How has Facebook’s new Open Graph integration gone for its music service partners? The social network published some stats last night. “Since f8, people have shared their listening activity more than 1.5 billion times with their friends using the music apps that have integrated the Open Graph,” writes Facebook’s Casey Muller. “As a result, some of our biggest music developers have more than doubled their active users, while earlier-stage startups and services starting with a smaller base have seen anywhere between a 2-10x increase in active users.” Specifics? Spotify has added more than four million new users while Deezer has been adding more than 10,000 users a day, but all the other figures given are percentage increases: 246% more Facebook users for Mog, 30x more new user registrations from Facebook for Rdio, and 11x more monthly active users for Slacker. Facebook also claims that ticketing sites have seen between $2 and $6 in direct ticket sales for every link shared on Facebook, while Vevo doubled its daily active users on 20 October when featuring videos from Justin Bieber and Rihanna.
