The Vodafone Group is to launch a new streamed music service. The company has joined forces with Sony NetServices to provide the Vodafone Radio DJ service, which will provide personalized music channels streamed to customers' handsets and computers.

A key feature of the Vodafone service is a personalization system that enables customers to "train" preprogrammed channels to their own personal tastes by simply pressing a button to indicate "like" or "dislike" while listening to a song. When pressing "dislike," customers automatically skip to the next song, according to Vodafone.

Users can also create their own personal channels.

Available for a fee through the Vodafone Live portal, the new service requires handsets using packet-based technologies, such as GPRS or 3G.
