4. Billie Eilish

Usually when someone first discovers Billie Eilish, her age is always a shocker. The 17-year-old has had one hell of a year with a debut album and hit single that destroyed the charts. “Bad Guy” solidified Eilish’s place in pop music mastery. It’s hard to believe nearly three years ago she was paving her way at the mere age of 14, attempting to find her voice. We remember her 2016 single “Ocean Eyes” — Eilish’s angelic vocals took over our speakers and reminded us that talent can still be revolutionary even at a young age. Now she’s a Grammy-nominated artist predicted to steal the entire show.
