Sony BMG Music Entertainment, the world's second largest music company, will this month become the last of the big four majors to drop copy protection software on music downloads, also known as digital rights management (DRM). Sony BMG, home to artists including Beyonce, Britney Spears and Celine Dion, said on Monday it will launch a gift card service on January 15 called Platinum MusicPass that will feature digital albums from its artists in the MP3 format. The format does not use DRM protection. Fans will be able to buy the digital album cards in stores and download full-length albums from a MusicPass Web site after they type in an identifying number. The cards will be available at U.S. retail outlets such as Best Buy and Target.
