Share 'Mainstream Hate?'

I've always listened to underground and never really took the time to listen to mainstream stuff. I've heard black and yellow, and some other stuff but I didn't listen to them cause of the beat.

Is it just the DJ's or is it the rappers themself?   To my knowledge rappers don't like the people that actually run the music industry…
