I dont think people beefin over Cam'ron. Its the ignorance of certain people, who are making judgements over something they havent heard based on there own closed minded perceptions.
Today already i bumped the Bo and Lynch cd, sum Project Pat, Luni Coleone and Damu, Z-Ro, Red Head Steve, Shyne and the new Cam'ron
Its all tight rap to me, even though they all from different areas and get different amounts of exposure.
The thing that makes something more mainstream than another is the amount of money put into marketing it.
LBI hit the billboard charts, and if the promotion of the first single was big enough, theres a good chance it would have been played on commercial radio. It doesnt make it any more or less relevent as a piece of music.
