No. 5: Soulja Boy Tell 'Em

Birthdate: July 28, 1990 (age 20)

Why He's Hot: Recent Kat Stacks drama aside, Soulja Boy remains high on our list of young hitmakers. The rapper/producer shot to fame in 2007 with his single "Crank That," which sparked an accompanying dance craze and became a Hot 100 No. 1 hit. In the three years since, Soulja (aka DeAndre Cortez Way ) has notched three more top 20 singles on the Hot 100 chart and released and a pair of albums that hit no. 1 ("Souljaboytellem.com") and no. 2 ("iSouljaBoyTellEm") on the Billboard Rap Albums chart. Soulja is readying his upcoming album "The DeAndre Way," due Nov. 2, and recently signed rapper Lil B to his SODMG label.
