Google Music has been an invite-only service since it was launched early this year. I have been using the beta service for quite some time now. You can check a video of it in action.
I have 1 invite to send to anyone. If you are interested to try it out, like our Facebook (http://www.facebook.com/techoloph) and comment here. I’ll pick the winning candidate by next week. Be sure to leave your email! (no spam format)
