TK and Draco the Ruler

Prosecutors alleged Draco the ruler was a part of a botched plot to kill a rival at a party he attended in December 2016. Allegedly in the midst of a shootout, he and his gang had accidentally murdered 24 year old Davion Gregory. But not withstanding his lyrics were used in trial as a means in which to establish a motive. How successful have prosecutors been using this approach to do the lyrics sort of tip to scales in their favor? Are they winning cases?
