Are you a Belieber? The child prodigy out of Canada was first found on YouTube. From there, Bieber became one of the biggest stars on the planet. Despite only being 24 years of age, we’ve seen Bieber transition from bubblegum child pop to more of an R&B singer. As a 15-year-old, seven songs from his debut album appeared on the Hot 100 chart (a mark no other artist has ever accomplished). With plenty of time to crank out more material, there’s no telling how high Bieber will eventually finish by the time he stops performing.
