In Hannah Montana: Music Jam on the Nintendo DS, girls are transported into the exciting and sometimes crazy world of Miley Stewart and her alter ego Hannah Montana. Playing as both characters, kids practice their musical talents, coordinate high fashions and live out their dreams of becoming a pop star in Hannah?s greatest musical challenge yet. To help her win this competition, players use their Nintendo DS touch screen to master instruments including lead, bass and rhythm guitars, along with drums. On top of everything else, a new and mysterious pop-star blasts onto the scene to steal Hannah?s thunder.
