Singstar Vol. 2 will feature a harmony duet mode: a new way of playing that allows two players to sing different lines to a song at the same time, showing off their harmonising skills. This is really your chance to showcase your talent and adds a new dimension to the SingStar experience! Special tracks have been included to showcase this new mode such as Kool and the Gang: Celebration, the Paul McCartney & the Frog Chorus: We all Stand Together and The Mamas & The Papas: California Dreamin’.
