Does Justin Bieber really need an introduction? Bieber gained fame on YouTube singing covers at the crazy young age of 12. By the time he was 13, big-time talent agent Scooter Braun invited him to record some demos and only a year later he got famous globally with his first hit single “one time”. Since then, his fame has only grown, with over 86 billion career streams and 78 million albums sold worldwide as of 2022. That, combined with his 75 million monthly listeners on Spotify, makes him one of the biggest artists in the world.
