What They Dissed: "Invincible" (2012)
What They Said: "First off, I hated the song when I first did it because it was brought to me by corporate America. So basically Jimmy Iovine was like hey, first off they didn't even come to me with the song, it was like a contest between the Interscope rappers like Yelawolf, Kendrick Lamar and myself, which I found out. It sucked and I hated it." - Machine Gun Kelly
Cleveland rapper Machine Gun Kelly definitely owned up to his "wild boy" persona early on, with the handcuff scars to prove it. So when it came time to pick out the first single to lead his Interscope debut Laced Up, naturally his label went with a pop record about personal perseverance backed by vocals from a singer better known for her work with Chris Brown. Okay. In retrospect, the record itself wasn't that bad, but MGK was also aware of the backdoor discussions that were occurring.
