In 2016, which rapper became the first musician to be inducted to the WWE Hall of Fame?

I know next to nothing about the WWE, but this question was fairly easy to answer, as Snoop's name and photo are in the upper-left of the picture of the "WWE Hall of Fame Class of 2016" included with the question. Also, featured nearby in that picture is Joan Lunden. Quite the eclectic celebrity mix of WWE HoF inductees that year.
