"iTunes offers customers a simple, one-click option to easily upgrade their entire library of previously purchased songs to the higher quality DRM-free iTunes Plus format for just 30 cents per song or 30 percent of the album price. The iTunes Store will begin offering eight million of its 10 million songs in Apple’s DRM-free format, iTunes Plus, today with the remaining two million songs offered in iTunes Plus by the end of March."
