Rock Band keeps rocking the downloadable content market as Harmonix announced today the game has sold over 6 million songs in just over three months. The title has set the bar for DLC with fresh weekly content and the last update we had about sales numbers stated that Rock Band had sold 2.5 million pieces of DLC around mid-January. We've placed a master list of all the songs available on Rock Band after the break.
Although we'll probably never get a straight answer, it would be nice to find out how much of an impact the new Rock Band music store is expected to make on sales. Having all that DLC available from directly inside the game, rather than making potential customers wander through the virtual aisles of the Xbox Marketplace or PlayStation Store, should make some noticeable difference.
