Google has just announced Google Play Music All Access at its Google I/O 2013 developer conference, the company's new subscription music service. Aside from givng you access to the millions of songs in Google's new streaming catalog, it will also incorporate tracks that you have stored in your Google Play Music account. The service launches today, and will cost $9.99 per month. Google offers a 30-day trial--sign up for the free trial by June 30th, you'll lock in a $7.99 per month rate, making it 20% cheaper than competing services like Rdio and Spotify.
It is expected that Apple will announce it's own streaming music service, possibly at WWDC 2013 in June, but rumors point to it being more akin to a Pandora Internet radio competitor than a full on streaming service where you can pick and choose individual tracks and albums that you want to listen to.
