The game's main career mode is called the Quest mode. It has players go through a campaign where they must defeat a mechanized creature called the Beast by helping save the Demigod of Rock. Players recruit characters by completing some songs in their genre. When successful, the character transforms into a warrior, receives a unique power, and is added to the band's roster. Other game modes are Quickplay+ and Party mode. In the latter one or multiple players go through different songs like in a jukebox, with the ability to drop in or out at any time. The Wii version adds DS functionality with the Roadie mode, which has been expanded to three different game modes and supports up to eight players simultaneously.
