It's really Canibus(Featuring DZK)... Canibus recently signed to the Warlab, a label owned by Bis's brother, and investors close to DZK... and is close to dropping his album...
Me, personally... I think it was dumbed down, because if you listen to both Canibus and DZK's tracks/albums they are known for complexity... but a lot of listeners don't want to hear that these days in a battle... That's why they went for more personal jabs at Em...
