As a music executive, he heads his own record label, Cashville Records, and is currently a member of the hip hop group G-Unit. 　　Around the age of 12, Brown began rapping. A few years later, he performed for Brian "Baby" Williams, co-founder of Cash Money. After several years on and off of Cash Money, Brown and fellow rapper Juvenile decided to leave the label for good in 2000 and go to UTP, where Brown stayed until 2003. 　　One of his early appearances was on the song "Memphis," where he was featured along with Three 6 Mafia, Project Pat, and other southern rappers. His deal with UTP later led to a meeting with New York rapper 50 Cent, who later signed him to G-Unit Records, under Interscope.
