I was pretty disappointed to discover that Google Music launched with only United States access. Google can be annoyingly slow in acting like a global media company at times - Google Voice still isn't over here. Despite my disappointment I understood why Google Music wasn't available in the UK.
Damn those licensing rights. This is what took Pandora out of the UK and kept Spotify from the US.
That's why I've been surprised to see Google Music in my Google+ stream. American users can share snippets of what they are listening too. Teasers. These aren't geo-targeted at all. Not only do people in the UK see these teasers but they can listen to the sample too.
What does that mean for the licensing rights?
If you're curious - you can geo-target your status updates in Facebook. Maybe this needs to come to Google+.
