Sony Music Entertainment said Tuesday it plans to use the Scour.com file-sharing service to promote songs from five of its artists. The promotion marks the first time Sony Music has offered its artists’ music through an online peer-to-peer content distribution network. Initial partnership was inked between Sony and Scour.com-parent CenterSpan Communications earlier this year.

As part of the deal, Scour users are able to listen to tracks from Five for Fighting, Flickerstick, John Mayer and Macy Gray on their computers for 30 days after downloading.

Deal also calls for the songs to be distribbed on Scour.com using CenterSpan’s C-StarOne network that securely distribs rich media files over the Internet. Windows Media’s digital-rights management technology is being used to protect the files.

“Sony Music Entertainment has always embraced new technology that furthers our artists’ reach, and CenterSpan’s C-StarOne delivery network will allow music fans to share the music that they love with their friends legitimately,” said Jim McDermott, SME’s senior vice president, operations and label relations. “Working with Scour.com gives us great promotional opportunities like this for our artists.”

CenterSpan is hoping the Sony deal will encourage the other major record labels to use Scour.com to distrib music content.

“Today, Scour.com is the technology and marketing showcase for our C-StarOne content-delivery network, where potential C-StarOne customers such as Internet retailers and ISPs … can experience the … performance of C-StarOne for themselves,” said Frank G. Hausmann, chairman and chief executive officer of CenterSpan.
