tbh- kendrick ddn't diss anyone today at all. In fact he might be the realist mc out there. He told all of them straight up "even though we're cool and we laugh and joke around and shit at the end of the day we're in competition with each other" in fact i think he was paying respects to them in a sort of way saying something like "you're up there and just so you know i'm coming for your spot" it's the people who weren't mentioned by name who should be worried and he did mention eminem in the song he called him one of the best mc's. But people act like this is the first time kendrick said something like this back in 2010 he did the same thing on his free style of monster by kanye "i'm the best rapper alive! Jigga man should’ve retired
i'm going after kanye, lupe fiasco and nas snoop dogg and mister andre, eminem, busta buss rhymes y'all better bust no more rhymes i’ma start busting your ass if you walk with a metro, then throw a bus on your ass!".
