Sina Weibo renewal their sharing music service named "Micro Music(微音乐)".
At this renewal, Sina Weibo user can upload their original music.
I think it's like a social music, it's helpful for non-major bands to get to know their existence and music. If a musician want to advance Chinese music market, "Micro Music" makes more easy to do so :-)
As Sina Weibo already start virual money and video sharing service, they already recognized their Weibo service not only information tools, but also platform for various services.
In this year, Sina weibo will definitely accelerate such a movement.
