San Francisco - Yahoo (NASD: YHOO) has announced that it will provide refunds to any consumers who purchased songs locked by digital rights management (DRM), which otherwise would have eventually become unplayable after the company discontinues support for the technology. Yahoo had initially not offered any compensation to patrons of its Yahoo Music Unlimited service who purchased song downloads; had they needed to reauthorize the tracks on a new computer, for instance, they would have found the songs unplayable.
