Pitbull is great with brands. Endorsements with hip-hop artists work because hip-hop artists typically set the most trends... It's every brand's goal to be seen in the mainstream, and hip-hop music has become mainstream music.
I initially wanted to work in the music industry more on the A&R side. While I was in school, I began working in the New Business department of an advertising firm, and very quickly I was responsible for roughly 70% of their business, so you could say I had a natural knack for the advertising world.
