Harmonix and MTV Games announced the Rock Band Network that gives musicians and record labels the ability to author their own original recordings into files that can be played and sold as Rock Band tracks. The tracks will be sold through the new Rock Band Network Music Store.

The Rock Band Network is set to launch in late August 2009 in the U.S. and will offer a toolset and detailed documentation on how to start the process of turning music into Rock Band files. Players will be able to demo samples of the songs before they purchase and the tracks will debut exclusively on the Xbox 360 for 30 days.

To publish Rock Band files the users will need a membership to Microsoft's XNA Creators Club and to access the Rock Band track service users will need the premium membership. The Premium membership costs $49.99 for four months or $99.99 for an entire year of access.
