Apple Launches iTunes Plus with DRM-Free Tracks
Today Apple launched iTunes Plus, a premium service that offers music tracks free of copy protection. The iTunes Plus service debuts, as expected, featuring EMI Group's digital catalog of recordings.
Apple says the copy protection-free music tracks will be available as high quality 256 kbps AAC encoded audio "virtually indistinguishable from the original recordings" and will sell for just $1.29 per song. That's 30 cents more than tracks with copy protection that sell on iTunes for 99 cents. The technology that is used to prevent music tracks from being copied and redistributed is called digital rights management or DRM.
Apple also says iTunes customers can now easily upgrade their library of previously purchased EMI content to iTunes Plus tracks for just 30 cents a song and $3.00 for most albums.
Apple will continue to offer EMI's music with the DRM technology and at its current audio quality, for customers who don't want to pay extra.
Easier Listening without DRM
DRM, which prevents consumers from copying music illegally, also creates what many see as unfair restrictions on the way consumers can listen to songs they have legally purchased.
Most notably, Apple's proprietary DRM system prevents people who buy songs from its market-leading iTunes store from playing them easily on any music player other than an Apple iPod. That restriction has attracted criticism, particularly from regulators in Europe who say it unfairly limits customer choice.
iTunes Plus includes EMI's digital catalog, such as music of Coldplay, The Rolling Stones, Norah Jones, Frank Sinatra, Joss Stone, Pink Floyd, John Coltrane, and Paul McCartney.
