Today, Vodafone and Sony NetServices are announcing a partnership for the global roll-out of the world's first fully convergent music service - Vodafone Radio DJ - offering interactive, personalised radio channels streamed to both 3G mobile phones and personal computers.

The key feature of Vodafone Radio DJ is its easy-to-use personalization system, which enables customers to "train" the pre-programmed radio channels to their own personal tastes by simply pressing a button to indicate "like" or "dislike" while listening to a song. If a customer presses 'dislike', the music skips to the next song.

Through Sony NetServices' detailed classification of each song in the catalogue - analysing beat and harmonies as well as genre and mood - the radio channels that individual customers receive will feature more songs that have characteristics in common with songs that are liked, whilst avoiding songs with characteristics similar to those that the customer dislikes.

The Vodafone Radio DJ service consists of three elements:

Pre-defined channels. Customers can select a radio channel based on mood or genre. If the customer indicates that they don’t like the song, the channel skips to the next track within the channel. Customers can also buy any songs that they like and these will be automatically available for download to their phone and PC.

Personal Channels. By rating songs on the existing radio channels, the customer can create a number of new, personal channels corresponding to their desired genres, moods or specific themes.

Collections. Vodafone Radio DJ also presents programmed collections of songs to the customer on mobile phone or PC. These collections will be created by local music experts around a theme (eg Christmas Hits, or the Best New Hip-Hop), be updated regularly, and will comprise about 15 songs.

Songs purchased on either mobile phone or PC will be available to download on both devices, with a separate high quality stereo copy being delivered individually to each. Personal settings and personal channels created on the mobile phone will also be accessible from the PC.

The Radio DJ service will be offered on the basis of a monthly subscription for unlimited listening to music on both mobile phone and PC. There will be no extra charge to the consumer for the data traffic needed to deliver the music to the phone or PC.

Vodafone Radio DJ will be launched in six European countries in the coming months, namely UK, France, Germany, Italy, Portugal and Spain. It is intended it will then be rolled out to more than 20 countries worldwide over the following twelve months.
