When the Wu-Tang Clan arrived in 1993, they rewrote the book on how Rap was to be done.  As a collection of MC’s, Wu-Tang became stars immediately and their collection of rappers would become the equivalent of a Rapping All Star Team. 

If you only know The Roots from their role as the house band on Jimmy Fallon’s late night talk show, than you really don’t understand just how important this group is.

This could be one of the most interesting Rap debates for the Rock and Roll Hall of Fame.

Shania Twain may not be thought of us a Rock Star, but often it is hard to really peg her as a Country Star either.  Shania Twain was at her best when she ventured into Pop with a Country flavor and as such she became a massive figure in popular music.  Her success was so big that she despite not having recorded any material in over a decade she could still do an arena tour today without supporting a new album.  She inspired many a crossover artist.  It may not be Rock impact, but it is an impact on popular music.  People have gotten into the Hall for less than that.
