Vodafone U.K. has pledged to launch its MusicStation application ahead of Christmas 2007, enabling users to download unlimited tracks to their handsets for a weekly £1.99 ($4) subscription.

The telecoms giant claims one million tracks licensed from the four majors and "leading independents" will be available to users of a range of 2.5G and 3G mobiles, through an exclusive agreement with U.K.-based mobile music company Omnifone.

The music majors have thrown their support behind the one-the-go offering. Rob Wells, senior VP, digital, Universal Music Group International, describes MusicStation as the "most compelling music experience on mobile today," and reckons the unlimited download model creates "the U.K.'s first digital music experience on mobile that has true mass market appeal."

Warner Music Europe VP, digital business, Eric Daugan, notes, "Pairing MusicStation's easy-to-use subscription service with Vodafone's base of 17.4 million U.K. mobile customers opens up an important new route through which our artists can connect with their fans."

And Mike McMahon, EMI U.K. and Ireland's senior VP, commercial and digital, claims the broader U.K. music market will benefit from the new digital revenue streams created by the service.

MusicStation features built-in networked functions which allow users to share playlists and tracks with others.

The service automatically stores playlists on the phone's internal or removable memory, allowing customers to retrieve songs if their phone is lost or stolen.
