I very rarely like children's singing. There's one exception because usually I like the girls who play Mary in The Secret Garden. I saw a college production recently and the girl who played her was fantastic.
But what I REALLY hate are boy sopranos. Gustave in Love Never Dies annoys me so much. I only can stand him when he's using his lower register.
Not to mention you get a weird feeling because you have to wonder if those kids are really there voluntarily.

Jimmy, what are you doing here in the middle of the night? It's almost 9 PM!
