Napster CEO Chris Gorog is predicting a migration from the iTunes-style pay-as-you-go system of online-music consumption to a subscription-based model similar to Napster's.

Gorog told USA today: "Filling a top-of-the-line iPod with 10,000 songs would cost $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 enormous value."

Yahoo's Dave Goldberg also supports the subscription model. He told USA Today: "Selling 99-cent singles isn't working as a business model for us or for consumers. We sell hundreds of downloads but we don't make money on them. Subscriptions is a much better business for us."
