Underground

the opposite of mainstream

underground rapper Canibus got some beef wit Eminem, who is mainstream.

Emcee

spelled out version of "MC" (Microphone Controller). basically, a rapper, mainly, a hip hop artist in the underground. most emcees drop the "MC" when they hit the mainstream & what not.

when Marshall Mathers was underground, he was known as MC Eminem, but since he's become popular, he's just plain old Eminem aka Slim Shady, ya got me?

Mainstream

basically, what's popular, like rap music in most ways.

most mainstream rap artists are entertainers, cuz they giv what the public wants, which is new ish!
