9. BSBD ft. Gucci Mane, Deniro Farrar, Nacho Picasso, & Mack Shine - "Keys"
The rapper lineup alone should grip you. With one hell of an eight-year resume, BSBD haven't worked with many mainstream artists. Gucci Mane is one of the few exceptions and “Keys” is a prime example of why the production duo should be bigger, making millions in a futuristic studio. Instead, they are the underground instrumental kings, one of a very few who can create a movie with simply sound.
