Yup. The deaths, especially that of 2Pac, 'caused an unnecessary overload of super thug rappers...which became too much and the rap game changed completely. Ja Rule came in around the right time, because he got to shine off the hard shit, then when it changed, he came with other shit (the duets and love songs). Gangsta Rap will always exist, but it was kicked out of the mainstream after those two deaths (even though the murders had NOTHING to do with music).
If it died when Eazy died, Pac's last two albums never would have been as big as they were. West Side Connection's first album wouldn't have been as big as it was, either.
