Listening to this song makes me think that Busta Rhymes has the all-purpose flow. I think his flow works over any kind of track out there.
This is clearly an attempt to out Kanye Kanye and it works, in as much as you understand and dig that Busta is an actual emcee. In that sense, there is no competition.
But unlike, say Snoop making a brilliant move to replace the "G" with a "P" in his Funk for Sexual Eruption, this song, catchy as it is, doesn't deepen or clarify who we know Busta to be.
