Japanese just love to dream, so they manage to come up with this manga/anime movie. The inspiring part about this show is that it brings a dilemma to the singer when he cannot sing the songs he likes to, but yet inspires others with the songs he himself disapproves. Yeah, subconscious talent or whatever you call it.
So in the end, does it matter if he plays the music he likes and doesn't get recognized? Or is it better to stay with something he can be good at and inspire others at the expense of his own dream?
Sometimes, fighting for your dream versus sacrificing your dream to make dreams for others.. it's really difficult to make a call.
