2Pac
Everybody knows about his feud with Biggie, but by the last year of his life, the legendary rapper was treating virtually everyone in hip hop like an enemy. His most famous disses were aimed at B.I.G. and Mobb Deep; and later on, Nas, Jay-Z and even De La Soul. But he also recorded many unreleased diss tracks. Among the targets of his rage? Da Brat, LL Cool J and, for some strange reason, the Fugees.
