For 11 year-old songwriting, it may be "fun," but no one should be encouraging those vocals. Even if the kid were grown up so he lost that tinny, cracking tone, that shit-style wouldn't so much as pass in the indie world, where most people aren't too concerned about extremely "nice" vocals, let alone anywhere else.
Also, they've got two other songs recorded (check the right sidebar) and another "coming soon." A stop should be made before it goes much further.
