Apple rivals say the iTunes Music Store’s 99-cent pricing is the wrong formula for digital music, and that subscription-based models are the future. With the top-of-the-line iPod, “You can fit 10,000 songs on it,” Napster CEO Chris Gorog says. But “to do that would cost you $10,000 if you bought the songs from Apple. With our plan, customers can get 10,000 songs on their device for $180 a year. It’s an enormous value.”
