When it comes to ranking celebrities, Forbes isn’t the only game in town. Billboard just revealed a list of their own. The music publication ranked the Top 21 musical acts under the age of 21. Given the number of musicians discovered by Simon Cowell, Billboard should really consider renaming their annual list in his honor. His acts bookend the list, with a couple sandwiched smack-dabbed in the middle.

If you’re like me, you’ve only probably heard of a few of them. That is unless you’re actually under 21. Check out which minor is a major player in Billboard’s eyes. Find out how One Direction, Miley Cyrus, Fifth Harmony, Lorde, Ariana Grande, Justin Bieber, Cher Lloyd and others rank. I’ve also embedded music videos from each act to familiarize yourself with their work.
