Well, what do we have here? It looks like Google Music (beta) is finally allowing for users to invite friends to join Google’s music streaming service. So let all your friends and family know that they can upload their entire music library and no longer have to worry about precious sd card space.
Don’t have any friends (like me)? Well, maybe we could start a request thread in this post ala Google+ and see if anyone is generous enough to send you an invite. Oh- and Google Music is only available for U.S. residents. Good luck!
