Google has launched its very own music streaming service Google Play Music All Access in the U.K. , challenging long hailed competitors like Spotify, Deezer, Rdio and Bloom.fm.

Google Inc., world's largest search engine, launched its All Access music streaming service in the U.S. in May, and has now expanded its network in the markets of U.K., Austria, Belgium, France, Ireland, Italy, Luxembourg, Portugal and Spain.

Google has launched the "All Access" service in the already crowded market of the U.K., where people have long listened to Spotify, Deezer, Rdio and Bloom.fm. But Google has never shied away from competition.

The company has launched the service with a special discount for U.K. customers, which is valid for a limited period of time. New customers, who will join Google's music streaming service before September 15, will only have to pay around $13 (£7.99) per month, while other services cost more than $15(£9.99) per month.

"With today's launch, Google Play moves one step closer to your ultimate digital entertainment destination, where you can find, enjoy and share your favorite apps, games, books, movies, magazines, TV shows and music on your Android phone or tablet. Go ahead and start discovering a whole new world of music," Paul Joyce, Google Play Music's product manager, said in a Google Europe Blog.

Google launched its All Access music streaming service just ahead of the launch of Apple's iRadio.

Google's All Access allows users to add up to 20,000 tracks to Google Play library and an online storage locker that automatically scans computers for licensed music. It also "lets you create an ad-free, interactive radio station from any song or artist you love," Joyce added. Users can remove or re-order favorite songs and also browse to see the next play in the list, which is a new introduction in the service.

Google brings a dedicated Android app, allowing users to listen to music from their smartphones and tablets and even "pin" albums.
