Hmm.
Beat is sick, as usual from Rapitfly.
First guy was decent. Flow was decent, lyrics were pretty good but not in terms of concept. Comparing yourself to Biggie and Eazy?

But a decent verse.
Hook is decent but it needs making louder and having an effect or somethin added to seperate it from the verses.
SajN, i'm the last guy to hate accents but i couldn't understand most of yours without reading the lyrics. Work on your pronunciation. Lyrics were meh, the concept in general could be done by anyone. Your flow is decent but falls off many times.
I got to agree with SaJJad about this collab; Jay-19 is clearly more experienced, it's not fair to collab with a newcomer because you just completely outshine him.
Keep up though

Only way to go is up. I'd suggest getting a bit better before either of you (particularly SajN) post something.
