The Rock Band Network is a downloadable content service designed by Harmonix Music Systems with the help of Microsoft to allow musical artists and record labels to make their music available as playable tracks for the Rock Band series of rhythm video games. It was designed to allow more music to be incorporated into Rock Band than Harmonix themselves could produce for the games, and it is seen as a way to further expand the games' music catalog into a wide variety of genres. The Network started closed beta testing in September 2009, and an open beta test in January 2010. The Rock Band Network Store was publicly available on March 4, 2010 for all Xbox 360 players in selected countries (US, Canada, UK, France, Italy, Germany, Spain, Sweden, and Singapore). Rock Band Network songs will be exclusive to the Xbox 360 for 30 days upon each songs' release, after which a selection of songs will be made available on the PlayStation 3 and Wii.
The Rock Band Network is based on the XNA Creators Club model and uses peer review to check songs for playability, copyright violations and profanity in a song's lyrics. Harmonix has developed a suite of software tools, including a modified version of REAPER, a digital audio sound tool, and Magma, a metadata packaging tool, for use by artists and labels. In addition, Harmonix has helped to spawn the creation of several third-party companies, based on the previous hacking environment for the creation of custom songs, that will author an artist's song into a Rock Band track. Artists retain full control on their songs, and receive 30% of the sales from the Network. Several artists and labels have already committed to expanding the distribution of their music through the network. The Network has been considered a more favorable option for the addition of user-generated content for music games than compared to Activision's previous attempt with "GHTunes" for the Guitar Hero series.
