6. Lorde: 21 Under 21 (2013)
Last Year's Rank: N/A
Birthdate: November 7, 1996 (Age 16)
Why She's Hot: At this time last year, Ella Yelich-O'Connor was an unknown 15-year-old in New Zealand, still two months away from releasing her debut EP for free on the Internet. Fast forward one calendar frame, and one of the songs on that EP, "Royals," is a record-setting hit on Billboard's Alternative chart and a Top 5 single on the U.S. Hot 100. Its creator, now known as Lorde, is one of the most fascinating new talents in pop music, with sold-out shows, a beguiling debut album titled "Pure Heroine," and an astoundingly level head about her heightened profile. The head of Lorde's record label says that she could be "the artist of her generation," and thousands agree. It's time to hail Lorde with a spot in this year's Top 10.
