My problem with the flute in Spirit Tracks is not its usability but rather lack of integration. For such deep playability it feels tacked on. There are songs you play in duet and songs you learn and can play throughout the game... kind of. You learn a song to shine light, but you only use it twice in the game. You learn a song to call birds, but I think I only used it once. I just felt the flute was underused."
