Digital download store on Tuesday becomes the first major European service of it kind to offer Warner Music's repertoire in the MP3 format, through a new deal struck with Warner Music International.

An online marketing campaign will support the release program, through which various Warner Music albums will be temporarily offered for £5 ($10) to online customers in the U.K., or €6.99 ($10.60) in Spain, France, Germany and Ireland.

WMI has also agreed to partner with on a range of digital products and services, including album bundles containing exclusive content and artist web pages.

"This agreement," says John Reid, vice chairman, WMI and president, Warner Music Europe, "will not only enhance's service and expand our digital footprint but also benefit artists and music fans alike."

WMG ended its MP3 hold-out last December when it began offering titles to buy from Amazon MP3, the online retailer giant's DRM-free download store.

With the addition of Warner Music catalog, boasts a 3.5 million track catalog, of which 80% is DRM-free. The digital music firm recently secured investment of £4.25 million ($8.50 million) with a group of investors led by Sutton Place Managers, the proceeds of which will help expand its business abroad, particularly in the United States.
