Chad is a producer. I doubt this about Meek stealing his “style”. Meek Mill more than likely is using a beat produced by chad without paying him. Smaller producers get ****ed over by mainstream guys all the time. I’m just guessing that’s what he’s referring too.
Welcome to the music game. Drake has made a career off of riding new waves before they get mainstream hot. Kanye does it too. It's just a part of the game.
