In a move aimed squarely at luring iTunes customers, RealNetworks today announced that it has slashed song pricing to 49 cents and album pricing to $4.99 for a limited time. The price cuts are part of the company’s new “Freedom of Choice” marketing campaign to tout its Harmony technology, which allows songs purchases from the RealNetworks Music Store to be played on Apple’s iPod. The high-profile print, radio, and online advertising campaign kicks off Tuesday with a full-page ad in The New York Times that reads: “Half the price of Apple. Welcome to freedom of choice.” The ads also show an illustration of an iPod made to look like an open padlock. In addition, RealNetworks has launched a very anti-Apple blog. “This community site will provide a forum where consumers can learn about compatibility issues and discuss the issues with other digital music fans,” the company says.
