Mine would probably be this:You play as a DJ and you go around countries,planets galaxy's shooting cool beats and when you shoot some stuff (example:headphone) it starts making a beat that you wish and the story is:You want to become the best DJ ever and the last boss is Draft Punk feat. DEADMAU5!!Also the multi player could be this:You can make your maps and a mode where you face other players,the winner is the one who can make the better song,and the player waiting 2 play can listen and grade the players music!Post what you wish!I am OFF!
