The store will be Rhapsody's first venture to individual song and albums sales and a departure from the service's previous subscription model.
Users will be able to listen to full-song previews, rather than shortened clips, before purchasing a song. Real promised that most of the store's albums would cost US$9.99, while individual songs would cost US.99 cents.
Real also plans to partner with music channels VH1, MTV, and CMT to allow users to purchase songs from the Rhapsody store through the networks' respective websites. The company will also expand its wireless music service.
Real said that the move was part of a larger campaign known as 'Music Without Limits' designed to expand Rhapsody's reach.
"Until now, legal digital music has suffered from severe limitations on where consumers could buy it and how they could use it," said Real Networks chairman and chief executive Rob Glaser.
"Music Without Limits fixes those problems and will make digital music easier and more valuable for consumers."
