Roxio will announce key elements of its forthcoming Napster 2.0 service at a special conference today.

Apple director of marketing for applications and services Peter Lowe will give a keynote at the event. Lowe oversees product management and marketing for Apple's iLife applications, including iTunes, iPhoto, iMovie, iDVD, iSync, iCal, .Mac and Keynote. Roxio chairman and CEO Chris Gorog will also speak.

Announcing this Roxio said: "Napster 2.0 will be a legal, paid music service, and will be available to consumers by Christmas. Mr Gorog also plans to reveal that at launch, Napster 2.0 will allow users access to up to 500,000 tracks any way they choose: by paying for individual downloads, by monthly subscription, through Internet radio, or in any combination."

Gorog said: "Napster 2.0 is being built from the ground up to reflect the essence of independence and innovation that the brand is known for.

"Consumers want flexibility, and for the first time they will not have to choose between downloads or subscriptions. Napster 2.0 will allow music fans to do both, putting the power where it belongs – in the hands of consumers.

"We are pleased by consumers' continuing interest in the Napster brand, as evidenced by the very significant traffic we are receiving to our placeholder site at which allows consumers to sign up for updates on our progress and enjoy some creative teasers prior to the availability of the service. Our early prototypes of Napster 2.0 are progressing very well and we will be disclosing additional details as we get closer to our launch," Gorog said.

Roxio's Napster service already has content agreements with the five major labels and leading independents. The catalogue will feature tracks from Eminem and Miles Davis to the Dixie Chicks and Bob Marley, the company said.
