10. Eminem

Loudest Single(s): "Love The Way You Lie," "Space Bound," "The Way I Am" 

Complex says: Though he isn't always loud, Eminem displays plenty of aggression in his raps. And then sometimes Shady just snaps. His most emotionally loud-voiced record to date may be "Kim," from his 2000 classic The Marshall Mathers LP. We've noticed Em's become dramatically louder on a majority of the songs on Recovery too. We feel you, Marshall, but jeez—tone it down, dog. We don't want to blow out our Beats By Dr. Dre headphones.
