Warner Music International (WMI) has become the latest major label to sign up to ad-supported online music service Deezer (www.deezer.com), taking the French company's catalog to a claimed 3.7 million tracks.

Under the terms of the global content and revenue partnership, the WMI roster will be available to stream on-demand and for free on Deezer. The platform's advertising revenue will be split between the two companies; details of the revenue split are not available.

The agreement will also provide WMI with promotional opportunities across the site, such as editorial content management of its own artist pages, and links allowing users to purchase the music from specified online retailers.

WMI VP digital business Eric Daugan says he believes the partnership will expose Warner catalog to a wider audience and provide more opportunities for fans to get closer to their favourite acts. "We are now in a position to work with Deezer and third party advertisers to monetize a wide range of listening habits and to create online events and products that connect our artists with audiences in new, exciting ways," said Daugan in a statement.

Effective immediately, the French music service has made the WMI tracks available in its home territory. The company plans to extend the offer onto its operations in the United Kingdom and Germany by early 2009.

Deezer, which also carries material from Universal and Sony BMG, is France's first "music on demand" Web site for free, unlimited and legal music. Launched in 2006, it currently claims over three million members in total.
