Reason #7: Justin Bieber's next project is likely going to be a career-defining album.
A few times on this list, we've made mention of the fact that Bieber is a grown up now, or at least trying to act like one. So we're expecting a non-PG album out of him—one that could very well define where he is headed as an artist in the future (Think Timberlake's Justified). He's already an international superstar. But if his fourth album lives up to the hype, it could very well make him a respected artist among more than just teens and solidify him as a legend in the pop world.
