On Wednesday, Android head Andy Rubin said that Google’s Music Store will offer a special “twist” that will separate it from its competitors. Speaking to Business Insider, an anonymous record industry source said the “twist” is that Google Music users will be able to share songs with other users “on a limited basis.” Reportedly, the catch is that users will need to purchase the song first and friends will only be able to listen to the track for a limited amount of time. The service reminds us a lot of Spotify, which allows users to share tracks with one another for free. However, the free version of Spotify requires a user to listen to an occasional advertisement unless they sign up for one of two monthly subscription options. It is unclear when Google will launch its Music Store, but rumors have suggested it could make its debut this quarter.
