Here's a suggestion: Up All Night by Faze & Coogi Dollaz is a 2009 Jerk anthem produced by Jaynari of that New Boyz single with Ray J/the League Of Starz production collective fame which was featured on Mustard's own 2010 compilation Let's Jerk. Let's just say it features numerous sonic tics that have gone on to be the hallmarks of Mustard's production and it should put any suggestions that Mustard bit his whole shit from HBK Gang to rest for good.

If you're a rap geek who cares about boring trivialities like production credits, it's handy that you can now pick up cool little '00's CDs like Let's Jerk for the price of a supermarket sandwich, especially since there's still a market for flogging rubbish '80s and '90's rap CDs to Japanese kids who'll pay silly prices for any old shite as long as it's #RARE. I'm still spendin' money from 2008 when I sold some lad from Sendai my copy of Ice Cream Tee's awful 1988 album Can't Hold Back.
