Jay Z

Magna Carter Holy Grail wasn't Hova's strongest record, but that didn't stop it from going double platnium, thanks to a partnership with Samsung that moved a million units on the first day of its release. It's proof that the now hyphenless Jay Z is a businessman who happens to be a rapper. While marriage and fatherhood seem to have mellowed the Brooklyn emcee, he's still a formiddable presence onstage-even without Justin Timberlake in tow.
