Breh, they don't LET Puff do anything. Ya'll would be surprised who does what in a studio and how credits are broken down. Artists have gotten production credits for finding samples, turning down drums, adjusting elements in a beat. A lot of you just have no idea on how music is made.
It is clear you are a casual because:
1) You clearly do not understand how credits work
2) You do not know how production works
Who has gotten a production credit for turning down drums besides Bluff
