Turntable.fm has received plenty of press in 2011 from its avatar-based social music service, but one downside is that friends need to be online at the same time to listen together. New site Beatrobo takes Turntable.fm’s idea and makes it asynchronous, with rooms full of avatars based on Facebook friends, pulling in YouTube music videos based on their Likes. Requests can be sent between friends to be acted on when they come back online: for example “Do you know a good Christmas song?”. According to TechCrunch, Beatrobo CEO Hiroshi Asaeda says his service is more like a social game on Facebook, which are generally asynchronous in this way. Beatrobo is now live in beta. As far as we can make out, the service works outside the US too.
