No. 2. Tyler, The Creator
Birthdate: March 6, 1991 (age 20)
Why He's Hot: Tyler, The Creator may have arrived on the national consciousness when he won the MTV Video Music Award for Best New Artist in August, but the fearlessly aggressive rapper was making waves on the underground hip-hop scene long before jumping on the VMAs stage. The Odd Future Wolf Gang Kill Them All leader has released a pair of solo albums, "Bastard" and "Goblin," that have been just as widely hailed for their menacing lyricism as they have been criticized for their violence and misogyny. "Goblin" scored a surprising Top 10 debut in the Billboard 200 last year and its lead single "Yonkers" amassed a hefty 25 million YouTube views. Before Tyler turns 21 next spring, the rapper will continue touring with the rest of Odd Future, where he'll continue draw shocked reactions from unassuming rap fans across the globe.
