25. Meek Mill

Loudest Single(s): "Ima Boss," "Work"

Complex says: It wasn't until Meek Mill went from unsigned South Philly spitter to Rick Ross' Maybach Music Group representer that we started noticing an increase in his decibel count. Just compare his 2007 track "In My Bag" from his Flamerz mixtape to his 2011 summer anthem, "Ima Boss." You can certainly hear this kid's excitement about this rap shit. Must be that MMG money.
