And now, one of the most anticipated I/O announcements. As rumored, Google has been working toward the launch of its own music-streaming service, and the official unveiling came today. Dubbed Google Play Music All Access, the product has a strong focus on personalized recommendations via the so-called Explore feature. Like Spotify and other services, All Access will let you start a radio station while listening to a particular track, and in-depth tweaking controls allow you to nix songs that don't suit your fancy. Another feature demoed onstage is Listen Now, which highlights new releases and content Google thinks you'll enjoy.

As anticipated, All Access will require a monthly fee. A subscription costs $9.99 in the US, and all users will get a 30-day free trial. The service is launching stateside today, and if you sign up before June 30th, you'll get $2 off the monthly fee. We'll be taking All Access for a test drive as soon as possible -- check back for our initial impressions.
