"This milestone reflects a tremendous amount of hard work from the world-class teams at Harmonix, MTV Games and at our artist, management, label and publishing partners."

Rock Band delivers content in a variety of unique ways. Fans can access content included on the disc of Rock Band 2 and export other discs into their music library including Rock Band, LEGO® Rock Band, and a variety of track packs, which employ the disc export technology that Harmonix pioneered. Additionally, players can select from weekly downloadable content, now in its 105th consecutive week, all created by the dedicated Harmonix audio and art teams.

To date, Rock Band fans have downloaded more than 60 million songs from the Rock Band Music Store, and coming soon, Harmonix and MTV Games will be delivering new content via the Rock Band Network, a new suite of tools that allow bands and labels of all shapes and sizes to author their songs into downloadable, playable Rock Band tracks available for sale.
