On Wednesday, Andy Rubin, our fearless leader of Android, said that Google’s Music Store will offer some kind of special “twist” that will differentiate it from other music store competitors. When speaking to Business Insider, an anonymous record industry insider said the “twist” is a new sharing feature that allows Google Music users to share songs with others “on a limited basis.” Apparently, the catch is that once users purchase a song and share it with friends, the friends will only have a limited time until the sharing will expire, teasing them just enough to make them want their very own copy. This record industry insider also said that Google Music will allow users to “pin” songs to their device, essentially caching songs for play when no network connection is available.

This type of service reminds some people of the free version of Spotify, a music service that also allows users to share music but with the occasional advertisement sprinkled within. Like Spotify, Google must be paying major record labels a large sum of up-front cash to get these kind of rights, smaller indie labels are reportedly not getting any extra funds.

The record industry insider also said that Google Music will allow users to “pin” songs to their device, essentially caching songs for play when no network connection is available, but won’t have on-demand caching like that of other paid subscription music services. It is still unclear as to when Google will launch this new service, but rumors suggest it should arrive sometime this quarter.
