Born Corey McKay in Queensbridge, New York, Cormega is a rapper from Queens, New York, and participates in the New York rap scene. He was a prolific drug dealer before he began professionally rapping. His roots are similar to those of Brooklyn, New York rapper Jay-Z.

He was signed to the American record label Def Jam.

He has released Legal Hustle and the 2-Disc Realness/The True Meaning.

He collaborated with Nas in the early 1990's and was poised to be included in the New York supergroup of 2000 called The Firm which dropped one hit single, but was switched for another artist, Nature . No reason was given.

Nas dissed him on his 2001 song "Destroy and Rebuild" about the rap scene of Queens, and the two are still currently at odds:

Lyric:
Corey changed his name to uhh...whatever
pawn-chip, buckwheat, lookalike? Its Mega.
Right. Mega was his name, sorry bout that,
But its so hard to put a cowards name in my rap,
Always actin tough, a dopesta who be frontin,
He got snuffed, he got shot in the thigh, he did nothin

Continued later in song:

Back to Cor - got him a deal but his rhymes was whack,
Def Jam mad that he signed the contract,
Now he got jealous and mad at my shine,
Makin silly tapes, Im always on his mind.
Nonsense, not to be obnoxious kid,
Mega for the record you can s**k my d***.
- Nas
