This is a drake diss

Drake's record sales and streaming dominance still crushes Kendrick's, so maybe a better phrase would have been still killing it?

I listened to the tracks and Drake just has more poise.

Artistry? Maybe Kendrick? Too early to say, imo. There's lots of arguments for/against both artists as to why one is better/worse.

I think it played out at a time when national sentiments were running prrtty high, so it's really hard to make broad stroke judgement about whose tracks have better artistic merit. I found it funny how it all played out.

No. But given there are several articles already written on it on other crapto news sites and the actual context of his lyric, I'd say chances are pretty high.
