In a Monday statement, the Swedish digital music service Spotify said that its music streaming service has been extended to mobiles – as it has worked out an agreement for the launch of the mobile offering on the Apple iPhone and iPod Touch; as well as phones using the Google Android platform.

With the availability of Spotify’s mobile application, nearly four million tracks will become accessible by the company’s premium subscribers in the Sweden, UK, France, Spain, and Norway on the three mentioned devices, and by the iPhone and iPod Touch owners in Finland.

In addition, over 3,000 songs can be saved by users, for offline playing of these tracks. However, though the Spotify application will be free to download, it would necessitate a premium Spotify subscription of almost £10, unlike the company’s free streaming service for computers.

Furthermore, the Spotify music streaming service allows users to either listen to the tracks for free and in return for watching adverts; or else they can pay a premium £9.99 monthly charge to avoid the ads.

Talking about the newly-launched mobile app, Gustav Söderström, Spotify’s director of portable solutions, said: “This is a hugely significant day in Spotify's short history. Since our launch last October, we've worked hard to provide our users with a high quality service that gives them access to whatever music they want, whenever they want it.”
