The Swedish music streaming service Spotify aims to launch its first mobile application within weeks.

Spotify, a digital music service offering instant access to millions of tracks, has submitted an application to Apple's iTunes App Store for its approval, the Swedish company said on Monday.

The new app would allow iPhone users to stream playlists and save up to 3,000 songs to their handsets. If approved, it would be another groundbreaking step for the music service, launched last year, which gradually is rolling out its concept across the world.

Spotify has more than a million users in the UK, and more than six million across Europe. And it's soon to be launched in the US.

“Spotify is set to take America by storm, and the streaming music service could soon do the same to the iPhone platform”, American gadget magazine Wired wrote as the news was released.

The planned iPhone application would only be available to Spotify's premium customers if approved. Music fans can sign up for the company's ad-supported free service or a premium service with no commercials that costs 9.99 euros a month.

"The demo (application) is currently under evaluation ... so there is no specific launch date for it yet," Spotify's Annina Svensson told AFP.

"We are very confident. We have top level contacts at Apple directly and we are still talking to them," she added.

However, Spotify is a potential threat to Apple's music store and has been named an “iTunes killer” because of its ease to use and free library of millions of songs.

It has also been described as the savior of the music industry since it’s all legal and copyrights holders and music publishers are getting paid.

The iPhone application "should be available in a few weeks" according to a statement.

Spotify is currently only available in Sweden, Norway, Finland, Britain, France and Spain.
