For the time being, we’ll definitely have to file this one under rumor but our fingers are most certainly crossed. According to 9to5Mac’s “hunch”, which we would hope to mean anonymous reliable source, Sony BMG will soon become the second major label to get on board with Apple’s iTunes Plus offering. iTunes Plus, for those not keeping score at home, is Apple’s name for higher quality DRM-free tracks offered through its store. If this rumor pans out, Sony BMG will join EMI in making 256kbit DRM-free tracks available through iTunes. Apple launched the iTunes Plus service back in May of 2007 and initially charged a premium of 30¢ per track before seeing the light and lowering Plus prices to the normal 99¢ price point. Since then however, lack of major label adoption beyond EMI has kept the world pretty quiet about Apple’s DRM-free library. News of Sony BMG jumping on board would definitely be a huge knock against DRM and might help the other two majors, Universal and Warner, see the light.
