<p>How can you compare the backstreet boys to Justin? Justin is like 100times more popular than them. Although they were popular, they aren’t really in his league. And plenty of people have tried to replace him, Rebecca Black Devin Fox etc. Take Chris Brown and multiply his fan base by 20 and you get Justin Bieber. Chris Brown is still going strong after 6 years or something, I doubt Justin won’t.</p>
