Jumping into an already crowded music space, Google announced its rumored music service, Google Music All Access, in a keynote at its developers’ conference Tuesday.

The service, which lets users listen to tracks on demand and forms “stations” of related songs as you listen, will cost $9.99 per month. Early users, who sign on to the service before June 30, will be able to pay $7.99.

All users will get a 30-day free trial to try out the service, That’s a good move for Google, which may have to work hard to lure users away from music services that offer free, ad-supported plans such as Pandora and Spotify.

While Google has loaded up Google Music All Access with slick features such as the ability to easily edit or reorder playlists, the company didn’t offer many details about the service that seem to separate it from the rest of the pack — particularly given the fact that it’s only offering a paid version of the service.

The few advantages it does have are mostly for people who are already heavily plugged into the Google ecosystem. For example, the service will blend with the tracks users may already have stored at Google’s cloud music locker.

In the keynote presentation, Google executive Chris Yerga said that the service will make personal music recommendations for its users, who can also dig down into the service to find more songs based on attributes such as artist of genre.

The service is available on Android devices and over the Web. It will launch in the U.S. first, Yerga said, adding that company is working to roll the service out in other countries soon.
