The Spotify iPhone app launches today

SPOTIFY, the online music streaming service, has gone mobile with more than six million tracks now available from your handset.

The company launched a new paid-for application which means users of Apple iPhone, iPod Touch and Google Android can listen to their favourite music, wherever they are.

Daniel Ek, the founder and CEO of Spotify, said: "Never before has this much high quality music been so easy to enjoy.

"The new apps for Apple and Google phones mean our users can get the best of both the online and offline worlds, making it even easier for them to listen to all the world’s music, anywhere on the planet.

"You can search for any track you want or any artist you want."

Spotify has became an online sensation as it allows users to have free access to millions of songs – from opera to today’s charttoppers.

The service is available to premium customers who pay £9.99 a month.

There were doubts that Apple would agree to the deal , amid concerns it would compete with their iTunes store.

But Ek said all sides were happy with the arrangement.

He said: "Both Apple and Google have a strong application that will drive more people to use their respective operating systems and hopefully more people will buy new devices as well."

Ek hopes that expanding Spotify onto mobile phones will mean more money for the music industry.

"I look at this as a win-win in the sense that we're talking about paid-for music, so it can only be a good thing."

Ben Camm-Jones, news editor at Web User Magazine, said Spotify's launch into mobile phones would be popular - as long as the cost is not an obstacle.

He said: "You pay a tenner a month and get unlimited music. It is something that will benefit music fans greatly, if they're prepared to pay that money for it."
