I honestly don't get people saying he's "fake reacting" or heard these songs before....he's explained several times that his parents were never into hip-hop and his brother listened to a lot of underground shyt, which is how he heard that Immortal Technique song.
I see people saying "but maybe he heard these songs during a commercial, movie, etc."....which is

because that's literally the case with this Black Sheep song....he mentioned he'd heard the hook before, and I'm sure he has since it's been used in commercials. That don't mean he's gonna go Google the song....why would he?
