theres 2 parts to this game really
u basiclly pick songs for the characters to sing in a Glee club-ish situation and a reson why you picked the song. I can't really describe it heres 2 example:
player 1: tadase and amu have to sing a song together, what do they sing?!?
player 2: the sing taylor swift "Love Story" because in the song the girl says you be the prince & i'll be the princess and tadases a prince!
Player 1: Utau has to sing a solo expressing her feelings, what does she sing?
Player 2: she sings taylor swift "You belong with me" because it kinda explains the Amu-loves-Ikuto-but-so-does-Utau" situation
PART 2 (optional)
give a song expressing there lives so far to the characters on the list below:
(u don't have to do all the characters!)
Rima: Concreate Angel
Tadase: Viva la vida
Utau: you belong with me
