Pannon deal marks fourth in Europe.

Mobile-music provider Chaoticom Inc. has clinched a full-track download distribution deal with cell-phone operator Pannon GSM Hungary. It is Andover, Mass.-based Chaoticom's fourth such deal in Europe.

The new offering, which goes live commercially today (Oct. 20), enables Pannon to sell entire tracks as downloads to handsets; it will form part of the operator's djuice music service.

Content for the service is supplied by Warner Music Hungary, BMG Entertainment and London-based independent label V2. Chaoticom, which powers the service, says it is in talks with Sony Music Entertainment, which recently merged with BMG, and other labels for a broader repertoire in Hungary.

"We license, host and deliver the content, and integrate it with Pannon's billing system," explains Adam Sexton, Chaoticom's VP of marketing and product management.

Pannon customers can browse for CD-quality tracks and preview songs before making a selection via their mobile phones or through Pannon's Web site. Individual tracks cost €2.44 ($3.00).

The agreement also allows Pannon to offer Chaoticom-created master ringtones and wallpaper.

Chaoticom already supplies full-track downloads to three other European mobile networks: Orange in the United Kingdom, Telenor in Norway and Eurotel in the Czech Republic. It expects to announce its first agreement in Asia next month.
