1. Justin Bieber
The heart throb of millions of people around the world, Justin Bieber checks in at the first place on this list as the top pop singer in the world in 2012. At 19, Justin Bieber has achieved it all: won medals, trophies, awards and the love and recognition and so much more. Simply put, Justin Bieber, still being in his teens, has done more than any singer could ever dream of accomplishing. While I'm not a fan of Justin Bieber myself, I have to respect him for providing excellent music (or at least the music is excellent to teens) regularly. Justin Bieber's latest album, Believe, has got a lot of praise from the audience, and it is one of the most listened to albums in the world. The fans, the critics, and overall, the success he has received over the years has made Justin Bieber one of the best singers in the world. However, he is the best pop singer in the world, and in the future, he could easily become the best singer in the world. At 19, there's no stopping Justin Bieber as he continues to reach to great heights.
