Rock Band features the most downloadable content available, out of any console video game, period. About 900 artists are represented among those 2,700 songs – we cover a lot of ground in terms of genre and time period. We have everybody from Otis Redding to The Beatles to Fleetwood Mac to Metallica to Bon Jovi to Avenged Sevenfold to Green Day to The Ramones to Duran Duran and much more!
