Some analysts suggest that lifting the software restrictions could boost sales of online music, which currently account for around 10 percent of global music sales. Jobs said he planned to offer around half of all music in the iTunes store under the premium package by the end of the year, but declined to say whether the company was in discussions with other leading record companies.160Want local news?Sign up for the Localist and stay informed Something went wrong.

LONDON – Breaking from the rest of the recording industry, EMI Group said Monday it will begin selling songs online that are free of copy-protection technology through Apple Inc.’s iTunes Store. The deal, however, doesn’t include music from the label’s biggest act, The Beatles. ITunes customers will soon be able to buy songs by the Rolling Stones, Norah Jones, Coldplay and other top-selling artists for $1.29, or 30 cents more than the copy-protected version. The premium tunes also will be offered in a higher quality than the 99-cent tracks. EMI Chief Executive Eric Nicoli said The Beatles music catalog is excluded from the deal but the company was “working on it.” He declined to set a time frame for negotiations over the catalog. The announcement followed calls by Apple Chief Executive Steve Jobs earlier this year for the world’s four major record companies, including EMI Group PLC, to start selling songs online without copy-protection software. The technology, known as digital rights management, or DRM, is designed to combat piracy by preventing unauthorized copying or sharing, but it also can be a consumer headache. Some music players, for instance, support one type of DRM software but not others. The DRM used by Apple does not work with competing services or devices, meaning that consumers can download songs from iTunes to work only on their computers or iPod music players. The lock between the download services and players has drawn criticism from European industry regulators, who argue that it limits buyer choice. “Doing the right thing for the customer going forward is to tear down the walls that impede interoperability,” Jobs told a London news conference. He has previously argued there was little benefit to record companies selling more than 90 percent of their music without DRM on compact discs, then selling the remaining percentage online with DRM.
