Google has officially unveiled its new music subscription service, Digital Spy said.

Announced during the web giant's I/O keynote in San Francisco, 'Google Play Music All-Access' will be available in North America later on May 15 for $9.99 (£6.60) a month.

It will launch with a 30-day free trial, while users who sign up for the service before June 30 can subscribe at the discounted price of $7.99 (£5.25).

Described as a "uniquely Google approach to a music subscription service", users will be able to search categories, listen to radio and can even remove tracks from playlists.

"Music unites us. It's universal," Google's Chris Yerga explained. "With ubiquitous mobile devices, there's the potential to bring that joy with us wherever we are."

Google plans to roll the service out to other regions soon.

A music service was rumoured after Google signed licensing deals with Universal Music and Sony.

Google is believed to have signed a deal with Warner Music Group earlier this year, giving the company access to artists and songs from three major record labels.
