I haven't seen ANYBODY say that ghostwriting is uncommon.
That's Drake stans trying to point the finger at everybody else because he got caught with another mans hand up his ass all while trying to gain credibility as a
EMCEE.
Any of the supposed "flat top" "real heads" blah blah blah know what the deal is. Ghostwriting has been around from the JUMP, and so has been separating the wheat from the chaff when we start talking about who are the GREAT EMCEES in this culture.
Drake is now exempt from that conversation. Meep was except whether he uses ghost writers or not.
And as much as I love Cube he's been a sell out, not expecting him to switch it up now especially on a promo run involving the history on a group where it was mostly 2 people penning everybodies rhymes...he'd essentially be saying "fukk them, I deserve all the credit" to 2/3 of everybody involved
