Billboard’s 21 Under 21 2015: Music’s Hottest Young Stars

This year’s 21 Under 21 list — our annual look at the hottest artists in all genres who can’t yet legally purchase alcohol — includes bubblegum divas, punky boy bands, plucky country pairs, two types of rap duos, and one very large K-pop ensemble. And that’s just the beginning. The 21 creators celebrated below all make different types of tunes, but they’ve all achieved great things in their relatively short time on this planet.

Another thing many share in common is an industrious use of social media. The list is filled with young hopefuls who’ve parlayed YouTube and Vine stardom into much, much more. Of course, the Internet will only get you so far. The minors on this list have major talent, and that’s what ultimately got them where they are.
