Why not just have experts judge the music or stories? Don they know best?
Think, do you agree with every expert you read in the paper? And the problem with having just one expert judging the music is this: it’s just one opinion. I don’t know about you, but my friends have an entirely different collection of music than I have, and so be it. Different people have different tastes. We like having a range of opinions from your intended audience: kids.
