history: Justin Beiber seems to really jump in and out of the spotlight constantly. Yes, did you know he is from Canada? I did. Some of his music isn't too bad, but I don't care much for it. When did he start releasing music?
knowledge: After a talent manager discovered him through his YouTube videos covering songs in 2008 and signed to RBMG, Bieber released his debut EP, ''My World'', in late 2009.
