A full list of downloadable songs is available. The player can expand their music library on the Xbox 360 and PlayStation 3 versions by purchasing new songs offered on a weekly basis through the consoles' respective store systems.

The European version of the game also includes 9 additional songs that have since been released as downloadable content for other regions. Rock Band for the Xbox 360 and PlayStation 2 and 3 shipped with 58 songs on disk, while the Wii version, released at a later date, contained 5 additional songs that were released as downloadable content for the game. The gameplay in Rock Band is comparable to that in Guitar Hero along with elements from Harmonix' Karaoke Revolution. Rock Band expands on the concept by adding a drum and microphone peripheral, allowing up to four players to participate in the game, playing lead and bass guitar, drums, and vocals. Rock Band is based on Harmonix's previous success with the Guitar Hero series of video games in which players used a guitar-shaped controller to simulate playing rock music. The game is available for the Xbox 360, PlayStation 2, PlayStation 3, and Wii game consoles. Rock Band is a 2007 music video game developed by Harmonix and distributed by MTV Games and Electronic Arts.
