5. Waka Flocka Flame

Loudest Single(s): "Hard In Da Paint," "Bustin' At 'Em," "Lebron Flocka James 2 (Intro Pt. 2)"

Complex says: On just about every Waka Flocka song he screams atrociously loud ad-libs and raps. Ironically, the one record where his rapping is actually subdued is the song you'd think he'd be screaming the most: "Fuck This Industry."
