Caught In A Teen Dream
This decade is starting off with Justin Bieber, a decent enough teenager, who has the songs and a not-yet mature voice. Okay, as far as the latter I'm being kind. He has little voice. It actually sounds younger, and Bieber's only 16. Technology still helps young and old. Teenagers grow up and the acts have trouble adjusting to adulthood, that's why Teen Idol's don't last long, though I'm betting Cyrus can do it.
I like Bieber's chances only because his album is better than anything the JoBros have done. I'm not betting on him though. If his voice doesn't get any better he'll be musical history, but maybe acting will be his salvation. He could become the Hanson's who also crafted good Pop songs, but are now living in IndieLand.
