He's trying too hard with the technical part of it now. Every other line is some attempt to flip a cliche rap line or general saying into something new (that's ultimate corny as hell), or splitting words in half to the point that his flow has become choppy, or using corny similes that used to sound way better, etc. etc. It's not natural anymore. It feels like someone obsessing over the words at the expense of everything else.
The perfection of something like...
I'm so bananas I'm showin up to your open casket/
To fill it full of explosive gasses and close it back/
With a lit match in it while I sit back and just hope it catches/
Blow you to fragments, laugh, roll you and smoke the ashes/
...would never happen today. He'd ruin it with double time, wild voice tone changes, and trying to over-complicate the bars.
