       You love Jay Chou's songs and you can sing some quite well. So you make a video of your

performance and post it online for your friends to see. But what if this led to something beyond

your wildest imagination-a career in music?

      Canadian teenager Justin Bieber, 16, has just had the magical experience: He posted homemade

videos of his versions of songs by American singer Chris Brown online for his relatives. He received

a phone call from Brown, telling him how much he liked his performance. His singing eventually

earned him a fan base and a record contract. After releasing a popular EP (extended play密纹唱片)

record in November 2009, his album My world 2.0 came out last Tuesday.

      Bieber sings ballads and songs about puppy love. But is he just another gooey (甜腻的) teen

idol?

David Malitz, a columnist with the Washington Post, doesn't think so. "If we truly want the best for

American children, let us pause and give thanks for Justin Bieber, " he writes. "After years of humdrum

bubblegum (乏味的摇滚舞曲) from Miley Cyrus and the Jonas Brothers, the 16yearold has thrown

a candycoated wrench (扭转) into Disney's heartthrob (甜心) assembly line (生产线) by giving young

fans something worth screaming their lungs out for: lovable pop songs."

     From a boy who grew up below the poverty line with his divorced mom to a star who caused

nearriots (近乎失控) in shopping malls, even Bieber himself can't believe his overnight fame, although

his kind of success is becoming more and more common in the Internet era.

      Interested in hockey (冰球), the national sport of Canada, the boy once put up pictures of players

on the walls of his bedroom. He dreamed of being a hockey star and used to practice signing his

autograph (签名). He doesn't need practice now. He signs autographs, if the girls can get close enough,

as a music star.
