It's funny what passes for "legend" and "talent' these days.  One might be great at rap, but you're talking about a very simple and low form of entertainment that requires very little skill.

When I think of legendary and talented performers, for singers I would think of people like singers Barbra Streisand, Whitney Houston, Steve Perry, Robert Plant, etc.  Guitar players like John McLaughlin, Al Dimeola, Eddie Van Halen, Paco DeLucia.  Drummers like Billy Cobham, Buddy Ric, or Vinnie Coliuta.  Or Jaco on bass.

Putting this clown Eminem in that category is a joke.
